Creating RFC and Remote-enabled FM and call from another SAP system using ABAP

Program

Remote Function Module calling From SAP 4.7E to SAP ECC 5.0

Contents:

1.Goal

2.Step-By-Step for RFC

3.Step-By-Step for Function Module

4. Source Code of  ABAP Program

 

Goal

 

This assignment goal is to call a Function module from SAP 4.7E to SAP ECC5.0 through ABAP

program.

Function Module Goal: The Function Module Goal is to convert the data of  table into XML

format and save it in the system as xml format

Requirements: RFC Connection, Function Module Remote Enabled, Database Table for data,

LAN Connection betw een Both SAP systems.

Used sources:

RFC Destination = ECC5.0 f rom SAP 4.7E,

Function Module = Y_FM_IDOC_CATSDB (Remote Enabled

Module),

Database Table = CATSDB,

Fields Used From CATSDB

 

Fields Type Length

COUNTER CATSCOUNTE 12

PERNR PERNR_D 8

WORKDATE CATSDATE 8

----

STEP-BY-STEP FOR RFC DESTINATION

CREATION:(SAP 4.7E)

STEP 1:

IN SAP 4.7E call Transaction code "SM59".

STEP 3:

1. Type RFC Destination as "ECC5.0",

2. Select connection type as "3" for 3tire architecture,

3. Type Description for your Reference,

4. And "SAVE" it.

STEP 4:

1. Type Target host as your host name of the destination SAP (i.e.) ECC5.0,

2. Give the System Number of Destination system Number,

3. Select LOGON/SECURITY in tab str ip,

4. Give client no, Login id, Passw ord of SAP ECC5.0 if you know,

5. Save it.

Fig1.3

STEP 5:

To check connection click on 'TEST CONNECTION'

STEP 6:

To Remote Login click on 'Remote Logon'

Caution: It will logon only if connection is perfect (i.e.) Destination Host name and system

number is correct

and LAN is enabled.

Step-by-step to create Remote Enabled Function Module In SAP 4.7E

STEP 1:

1. IN SAP 4.7E call Transaction code "SE37", Fig 2.0

2. Select Goto --> Function Groups --> Create Group

3. Create Function Group by Giving FG name in Entry and Proceed

4. Type Function Module name in Function Module path after creation of f unction group,

5. Click on Create.

Fig 2.0

Step 2:

1. Select "Remote-Enabled Module" in Radio Button, Fig 2.1

2. Write descriptions for your referenc e,

3. Click on "Import" tab,

4. Fill the parameters name, type, Associated type as Field type from database table Fig 2.2

5. Tick on the "Pass value" check boxes for all entered fields,

6. Click on "Export" tab,

7. Fill the Parameters name, type, Assoc iated types ,

8. Tick on the "Pass value" check box for all entered fields,

9. Click on "Source code" tab,

10. Write the source code depend on your logics,

11. Save it, Compile it, activate it.

Source code of an ABAP program created in SAP ECC5.0 for calling SAP 4.7E Function

Module Remotely.

Note: If Function Module is not Remote-enabled Module then you cannot A ccess that Function Module of SAP 4.7E in SAP ECC5.0.

LAN is Important.
