Hi Everyone,

This is the second part of the blog Share the Knowledge - Optimizing SAP BW on SAP HANA Part 1

Best Practice # 7: Avoid Issues During Migration by  Using Automated Task Lists

We were told about optimizing System Migration

1.) Use the Checklist tool:It is recommended to run it before, during, and after migration for optimal insights

2.) Setup Task lists: use task lists for system preparation and system copy

3.) Run Post Migration Program

Go to Migration tab

After that a little bit intro about DMO was given

DMO(Data Migration Option) is an option of SUM (Software Update Manager) for a combined update and migration: update an existing SAP system to a higher Software Release and migrate to SAP HANA database.

To learn more about DMO check the below documents:

Migration to HANA made easy with DMO

Best Practice # 8: Validate SAP HANA Configuration,  Check Table Consistency and  Monitor Delta Merge

Use the Checking Tab of BW Migration Cockpit:

Rerun the checklist tool

Run Table Consistency check

Run Delta Merge Check

To learn more about Delta Merge process, check the below document:

Best Practice # 10: Tune Custom Code According to  Best Practices for ABAP on SAP HANA

Go to Optimization tab

Use ABAP Routine Analyzer that automates the check of best practice guidelines for ABAP routines in SAP NetWeaver BW systems focused on statements that can potentially be optimized for SAP HANA

To learn more about ABAP Code optimizzation for SAP HANA, check the below documents:
