SAP NetWeaver BW Migration Cockpit for SAP HANA Note 1909597 - SAP NetWeaver BW Migration Cockpit for SAP HANA

There are many transactions and programs to help you configure BW

on SAP HANA in an optimal way

The SAP NetWeaver BW Migration

Cockpit for SAP HANA provides

easy access to the

most used and useful tools

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in BW system grow over time •  Some data objects get inconsistent and corrupted •  BW systems become too large with outdated data •  System copy with inconsistent and outdated data will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 •  Delivered with SAP Note 1829728

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)


“Save Yourself Time…”

The „healthy“ system Don’t start thinking about data archiving when your system is about to crash!

Timely Planning Proactive action to prepare sustainable system performance

Interdisciplinary Process Data archiving requires a large amount of coordination between IT- and those responsible for applications.

• SAP HANA Agile Data Mart scenarios and SAP NetWeaver BW powered by HANA perfectly address the needs of, Data Marts and Central (E)DW

• SAP Sybase IQ is SAP‘s recommended NLS for SAP NetWeaver BW powered by SAP HANA and is capable of storing terabytes to petabytes of structured & unstructured data

• Mature customer architectures will leverage the capabilities of all three components where appropriate

Conclusion

The software upgrade manager (SUM 1.0) Framework including DMO �  The database migration option (DMO) is the “Plan A”, as there is no need for Plan B or better Option

(exceptions may apply)

Profit from end to end implementation roadmap that provides everything you need to know about the complete database migration process.

Shrink the database content prior to the database migration process � BW Housekeeping Tasklist (smaller ROW Store Footprint in HANA) � Data reallocation Process with SAP-NLS (smaller COLUMN Store Footprint in HANA)
