Usage of the ASU toolbox for BW When to call the ASU toolbox within the technical migration process

Check/first call before the start of SUM 1.0 - upgrade tool

DMO 1.0 - database migration option upgrade/in-place migration in one step

Post work starts before the SUM 1.0 - upgrade tool ends with step finalization

BW Housekeeping and Upgrade Before Tasklists Challenges with growing number of Data objects in SAP NetWeaver BW

Challenges:

• Data Objects in BW system grow over time

• Some data objects get inconsistent and corrupted

• BW systems become too large with outdated data

• System copy with inconsistent and outdated data will

result in inconsistencies

Solutions:

• Clean-up system regularly (e.g. monthly)

• Repair inconsistent data objects regularly

• Housekeeping especially before system copy

SAP NetWeaver BW - Key facts about NLS Interface

NLS Interface Features

• Supports archiving of InfoCubes and DataStore Objects

• Mainly time-based archiving, yet can also be based on other

characteristics

• Lock of the archived time slices in the original InfoProvider

• NLS Process Steps in Process Chain Handling

• Copes with changes in the meta data to the SAP NetWeaver BW

objects of the archived data

• Deletion of NLS partitions supported

• Direct load from ADK archive files into NLS supported

NLS should be a part of an Data Aging strategy

• Based on well-established SAP / BW archiving concepts

• Data consistency guaranteed before deleting the data from source

• Data archived in NLS can be incorporated into reporting

• Saves storage costs and other system resources

• High compression rate up to 90% (not on top of SAP HANA compression)

• Increases retention period for analysis data

• Included in the query statistic data collection (RSRT)

SAP HANA Smart Data Access Data virtualization for on-premise and hybrid cloud environments

Enhanced Business Flexibility by

providing “the logical EDW”

Data Federation in diverse EDW landscapes

• Smart data access – read access to relational and

non-relational sources via ODBC

• Enables access to remote data access just like

“local” table

• Supports data location agnostic development

• No special syntax to access heterogeneous data

sources

• BW based Analytic Services on external data

Scenario

• Make other DWHs transparent to HANA

• Non-disruptive evolution from virtual table to

persistent structure by establishing ETL without

major effort

• Consolidating / rationalizing the DWH landscape

• Consumption of HANA datamart scenarios from
