1 Stock Identification

Definition

Unique number that you use to identify stock (that is, a product) with all its stock attributes, such as quantity, batch, or stock type.

Use

When you perform goods movements in your warehouse, Extended Warehouse Management (EWM) creates a new warehouse task (WT) with a unique warehouse

task number (WT number) for every goods movement. If you have chosen the default value A (Stock Identification only if Externally Predetermined) or B

(Create Stock Identification if None Exists) in your Customizing settings, EWM simul taneously copies or creates the stock identification in every p roduct WT. You

can use the stock identification to choose the corresponding product with its quantity in the various user interfaces. In contrast to the WT number, the stock

identification remains unchanged even if you move the respective stock in the warehouse repeatedly. In this way, you can clearly identify stock during the goods

receipt and goods issue processes. When you confirm the respective WT, EWM saves the stock identification in the target stock.

Structure

The stock identification does not use a separate number range, rather it consists of a 16 digit number. The first four digits represent the warehouse number. The

other 12 digits represent the WT number.

The following figure shows this.

You can use the Business Add-In (BAdI) /SCWM/EX_CORE_CR_STOCK_ID BAdI:Number Assignment Stock Identification to create your own

numbering for stock identification. For more information, see the Implementation Guide (IMG) of Extended Warehouse Management under Business Add-Ins

(BAdIs) for Extended Warehouse Management Cross-Process Settings Warehouse Task BAdI: Number Assignment Stock Identification

Stock Identification in the GR and GI Processes

Purpose

The aim of stock identificationis to uniquely identify a stock, that is, a product, with all its stock attributes, such as quantity, batch, or stock type. For example,

you receive an inbound delivery with a mixed handling unit (mixed HU). In this case, the HU number is not sufficient for a unique stock identification. When

Extended Warehouse Management (EWM) creates warehouse tasks (WTs), it can simultaneously create corresponding stock identifications.

Prerequisites

In the Customizing settings for the warehouse process type, you have chosen the stock identification and there you have chosen the default value A (Stock

Identification Only if Externally Predetermined) or B (Create Stock Identification if None Exists) . For more information, see the Implementation Guide (IMG)

for Extended Warehouse Management Cross-Process Settings Warehouse Task Define Warehouse Process Type.

You have carried out the prerequisi tes for Using Stock Identification.

Process

The following figure provides an overview of the use of stock identification in the goods receipt and goods issue processes (GR and GI processes) in a stock

transfer between two warehouses.

In this process flow description, the names of the storage bins, the HUs, and so on, serve to provide a better understanding of the above figure. They are,

however, merely examples.

1. EWM has created an outbound delivery and the corresponding active product WTs in warehouse SPU1.

2. You pick stock for the outbound delivery from the storage bins JK01, JK02, and JK03, p ack i t into HU1, and confirm the active product WTs. When you are

picking, you can, if necessary, split the product WTs (see also Stock Identification When Splitting Warehouse Tasks).

3. EWM creates an active HU WT so that you can transport HU1 to a packing s tation. You repack the contents of HU1 into HU2 for the outbound delivery . EWM

creates corresponding product WTs that are confirmed immediately for repacking. You can use the stock identification to uniquely select the contents of HU1

that you want to repack. When you are repack ing HUs, you can, if necessary, split the stock (see also Stock Identification When Splitting Stock in the GI

Process.

4. You transport HU2 from pack station WS20 to GI zone WA20. EWM correspondingly creates an active HU WT for this shipment that you then confirm.

5. You load HU2 on to the truck and transport it from warehouse SPU1 to warehouse SPU2. EWM creates an active HU WT for loading that you then confirm.

6. You receive the inbound delivery containing HU2 in warehouse SPU2. You unload the truck and transport HU2 to GR zone GR10.

EWM creates an inbound delivery and the respective active HU WT that you then confirm. EWM creates different WTs for the GR and GI processes, for example,

a putaway WT WTNo.10001 and a pick-WT WTNo.2002. However, EWM creates putaway WTs on the basis of the stock identification of the supplying

warehouse, meaning that the stock identification does not change. You do not need to relabel. You can work with the putaway WT as well as selecting the

corresponding putaway WT via the stock identification to confirm it in a putaway process. (See also Using Stock Identification).

If you put two different stocks of the same product away, EWM transfers the unique stock identification, in other words each stock has a separate

stock identification. You do not have to print new labels. A prerequisite for this is that (in your Customizing settings), you have chosen the default

value A (Stock Identification Only if Externally Predetermined) or B (Create Stock Identification if None Exists) .

You transport HU2 from the GR zone to deconsolidation stationDS10. EWM correspondingly creates an active HU WT for the shipment that you then confirm.

You deconsolidate the contents of HU2 into two new HUs (HU3 and HU4) on the basis of the consolidation group. If necessary, you carry out a WT split. Using the

stock identification, you choose the corresponding inactive product WT and confirm the product in a possible destination HU.

7. EWM creates corresponding active product WTs while closing the destination HU.

8. You transport HU3 and HU4 from the deconsolidation station to the respec tive final storage bin, in other words, the storage type has the Stor.Ctrl/Put.Compl.

indicator, and you confirm the corresponding active product WTs. Here, EWM deletes the stock identification. When you start a new GI process, EWM creates

new unique stock identifications.

If you have already picked stock, it might be that you cannot yet post the GI, for example, because the truck has not arrived yet. If you want to put your stock

away first, you can carry this out using an ad-hoc WT. EWM does not delete the stock identification from the stock, although EWM has set the indicator for the final

storage type. This means that EWM checks whether the stock has another connection to an outbound delivery before the stock identification is deleted. If there is a

connection, EWM does not delete the stock identification yet.

Results

You have carried out a GI process and a GR process (stock transfer between two warehouses) with stock identification.

Instead of working with warehouse tasks (WTs) at various work centers in the warehouse, you can work with stock identification. Extended Warehouse

Management (EWM) finds the WT or stock that corresponds to the stock identification.

Prerequisites

You have carried out the prerequisi tes for Stock Identification in the GR and GI Processessapurl_link_0003_0002_0004.

You have set up stock identification. You have set the SI Control indicator.

For more information, see the Implementation Guide (IMG) for Extended Warehouse Management Cross-Process Settings Warehouse Task

Define Warehouse Process Type.

You have set the D elete Stock Identification indicator for final storage types.

For more information, see the IMG for Extended Warehouse Management (EWM) under Master Data Define Storage Type .

If you want to print labels , you have carried out the Customizing for Printing Warehouse Tasks.

Features

When you confirm WTs, you can select them using the stock identification.

To do this, on the SAP Easy Access screen, choose Extended Warehouse Management Execution Confirm Warehouse Task.

When you are deconsolidate a handling unit (HU) in goods receipt, you can select the WTs that are to be confirmed using the stock identification.

To do so, on the SAP Easy Access screen, choose Extended Warehouse Management Execution Deconsolidation in Goods Receipt. Specify

the organizational data Warehouse Number and Work Center and choose Execute . Scan the source HU and speci fy the stock identification in the Prd, SI,

WT, HU field on the Deconsolidate tab page. EWM finds the corresponding product WT using the stock identification. EWM disp lays either a possib le

destination HU in the product WT, or you specify a possible destination HU. You confirm the product WT with the possible destination HU.

If you want to repack stock, you can selec t it using the stock identification. EWM creates immediately confirmed WTs.

To do this, on the SAP Easy Access screen, choose Extended Warehouse Management Execution Packing - General. Specify theorganizational data Warehouse Number and Work Center and choose Execute . Scan the source HU and the stock identification of the products, that is, the

labels located within the HU. Go to the Repack Product tab page. EWM uses the stock identification to find the corresponding stock, in other words, EWM

displays the corresponding quantity. EWM proposes a possib le destination HU or a pack aging material. If you choose Execute , EWM creates an

immediately confirmed product WT containing the proposed destination HU as a destination storage bin.

If you want to count stock, you can select it using the stock identification.

To do this, on the SAP Easy Access screen, choose Extended Warehouse Management Execution Quality Inspection and Count. Specify the

organizational data Warehouse Number and Work Center and choose Execute . Scan the stock identification of the products, that is, the labels located

within the HU. Go to the Stock Details tab page. EWM uses the stock identifications to find the corresponding stock and display s the respective stock

attributes, such as product name or quantity.

If you want to enter count results, choose the stock us ing the stock identification. Enter the count results on the Counting tab page.

If you want to enter quality inspection results, such as findings or decisions, choose the stock using the stock identification. Go to the Q-Insp ection tab page

and enter the inspection results.

In user interfaces that support radio frequency, you can use stock identification for the following process s teps:

Deconsolidation

Packing

Counting Putaway

To do so, on the SAP Easy Access screen, choose Extended Warehouse Management Execution /SCWM/RFUI - Log On to RF Environment.

When you log on to the RF environment, you can work with stock identification in the following logical transactions only.

For deconsolidation, choose 03 Goods Receipt Processes 02 Deconsolidation 04 Deconsolidate Automatically or 05 Deconsolidate

Manually

For pack ing, choose 04 Goods Issue Process 02 Packing 04 Repack HU Item Automatically or 07 Repack HU Item Manually

During counting, choose 05 Internal Processes 04 Quality Management 04 QM Counting 03 QM Counting Results manually

For putaway, choose 03 Goods Receipt Processes 03 Putaway 01 Putaway by HU , 02 Putaway by HU (Clustered) , 03 Putaway by

Warehouse Order or 04 Confirmation Correction

See Also:

Work Processing Using Radio Frequency.

In the warehouse management monitor, you can search for WTs for the stock identification and for stocks for the stock identification. For example, on the SAP

Easy Acces Screen , choose Extended Warehouse Management Monitoring Warehouse Management Monitor . On this screen, choose

Documents Warehouse Task in the navigation tree. Specify a stock identification in the Stock Identification field in the Warehouse Task screen area.

If you work with stock identification, we recommend that you create a user-defined index (Z index) for both the table for open warehouse tasks

(/SCWM/ORDIM_O) and the table for stock (/SCWM/QUAN). This allows EWM to carry out faster search queries.

Stock Identification When Splitting Warehouse Tasks

PurposeYou can also use stock identificationfor putaway when spl itting stock for in the goods receipt process when splitting stock (GR process) and in the goods iss ue

process (GI process). Here, Extended Warehouse Management (EWM) creates WTs with new stock identifications. You can print labels showing the new stock

identifications.

6/7

Prerequisites

See Stock Identification in the GR and GI Processesand Using Stock Identification.

Process

When you confirm a WT with a partial quantity, a WT split occurs. EWM assigns a new stock identification to the split quantity. The following figure provides an

overview of the use of stock identification when splitting a WT in the GR and GI processes.

1. You have packed stock into a handling unit (HU), for examp le, HU1.

2. You only confirm part of the stock in the corresponding WT. For examp le, only six pieces fit into HU1 instead of the required ten.

a. You only confirm six p ieces in the WT, for example WT 1001/001, .

b. Depending on your Customizing settings, EWM spl its the WT and creates a new WT (such as 1001/002) with four pieces for the remaining quantity.

c. EWM assigns a new stock identification (such as AND198898) to the confirmed WT. This means that the two different stocks have two separate stock

identifications to ensure unique stock identification.

EWM only retains the same stock identification as in the original WT for the WT that was confirmed last.

3. You confirm WT 1001/002.

4. You print new labels for both stock identifications and apply them.

!--a11y-->

Stock Identification When Splitting Stock in the GR Process

Purpose

You can also use stock identificationwhen splitting stock in the GR process. Here, Extended Warehouse Management (EWM) creates new putaway warehouse

tasks (putaway WTs) with new stock identifications. For example, you receive a handling unit (HU) from a supplier, the contents of which has one stock

identification. You want to put this HU away and you determine that this requires two destination storage bins.

Prerequisites


Process

The following figure provides an overview of the use of stock identification when splitting stock in the GR process.

1. You receive an inbound delivery with an HU. For examp le, you receive an HU1 with ten pieces.

2. EWM creates the required putaway WTs in accordance with the putaway strategy, for example, putaway WT 4711 with six pieces and putaway WT 4712

with four pieces. If you do not confirm the putaway WTs immediately, both of them receive the available stock identification, for example, the stock

identification ANDI1001 and a new target stock identification each, such as SPU24711 and SPU24712.

3. If you want to search for putaway WTs for a stock, you use the stock identification to search for the unconfirmed putaway WTs for a stock. EWM then disp lays

all the corresponding, open putaway WTs. For example, you use the stock identification ANDI1001 to search for the corresponding putaway WTs. EWM

displays the putaway WTs 4711 and 4712 as the result.

7/7

4. When you confirm the putaway WT during deconsolidation for examp le, you can still sp ecify or scan the stock identification ANDI1001 that was printed on the

original label . EWM then displays the options WT 4711 and WT 4712. You choose one WT and confirm it. EWM then transfers the target stock identification to

the stock. If you have not done so already, you must now print new labels with the new stock identifications and apply them.

!--a11y-->

Stock Identification When Splitting Stock in the GI Process

Purpose

You can also use stock identificationwhen splitting stock for packing in the goods issue process (GI process). Here, Extended Warehouse Management (EWM)

creates new warehouse tasks (WTs) with new stock identifications. You can print labels showing the new stock identifications.

Prerequisites


ProcessThe process flow for using stock identification corresponds with the process flow for splitting WTs, in other words, that EWM creates a new stock identification for

every stock that is sp lit (see also Stock Identification When Splitting Warehouse Tasks.)

EWM only assigns the same stock identification as in the stock to the WT that was created last and confirmed immediately.

The following figure provides an overview of the use of stock identification when splitting stock in the GI process.

1. If, while you are repack ing products you realize that instead of being ab le to pack ten pieces of a product in an HU (HU1, for example) you are only able to

pack four pieces for example, you must carry out a stock sp lit. You can carry out the stock sp lit during repacking, thereby repacking with WTs that have

been confirmed immediately.

2. You reduce the default quantity from ten pieces to four pieces.

3. For repacking, EWM creates an immediately confirmed WT (2002, for example) with a new stock identification (AND19898 , for example) with the partial

quantity of four pieces.

4. For repacking, EWM also creates an immediately confirmed WT (3003, for example) with the remaining quantity of six p ieces with the original stock

identification (ANDI1001, for example). This ensures unique stock identification.

5. You print new labels for both stock identifications and apply them.
