More flexibility with SAP BW Post-Copy Automation

To reduce downtime for your production landscape, one of the recommended migration paths of SAP NetWeaver Business Warehouse (SAP NetWeaver BW) to SAP NetWeaver BW on SAP HANA comprises a system copy of your SAP NetWeaver BW system. The system copy procedure of SAP NetWeaver BW systems and landscapes is complex for a number of reasons however. A large number of configuration settings are involved for example (such as connections and delta queue handling for data loading), as well as system copy scenarios of SAP NetWeaver BW (each with different landscape aspects) that have to be handled as part of every system copy, regardless of whether the system copy is part of the migration to SAP HANA or you want to perform regular system copies of your SAP NetWeaver BW landscape.

To achieve this, SAP NetWeaver Landscape Virtualization Management offers preconfigured "task lists" used by the ABAP task manager for lifecycle management automation.

You can also enable SAP BW powered by SAP HANA to “go productive” with parallel operation of your existing production system, both connected to the same back-end systems. This is achieved with a special and unique automated solution for delta queue cloning and synchronization on production systems.

SAP Note 886102 (SMP login required) thus becomes obsolete. Using the post-copy automation for SAP BW (BW PCA) in the migration process of SAP BW to SAP BW on SAP HANA, this process can be shortened by weeks and becomes easier, faster and more reliable.

The former presentation TechEd 2014 - Session ITM206 still illustrates the migration to SAP BW on SAP HANA from an end-to-end perspective.

SAP BW 7.30  - Systemcopy ABAP => Update from January 2020

Since Release 7.30 SP05, it is now possible to perform a heterogeneous system copy (including unicode migration) to migrate existing systems based on SAP BW 7.30 SP05 and higher to SAP BW on SAP HANA (HDB) based systems.

With this major step forward, a new procedure called "Post Copy Automation (BW PCA)" now supports customers with what can often be complex post-steps before and after the homogenous/heterogeneous BW system copy. This presentation is the delta information to the existing document "SAP NetWeaver 7.30 - BW Systemcopy ABAP" shown above. The technical Improvements with the leaner data model provides advantages with BW on HANA too.

You can also refer to the SAP First Guidance Documents
- SAP First Guidance – SAP BW on HANA – Edition 2021
- SAP First Guidance - BW Housekeeping and BW-PCA

To ease this generic step of BW system copy, a new procedure called "BW Post Copy automation (BW PCA)" is available, which supports customer now in the complex pre and post steps during the homogeneous/heterogeneous SAP BW  system copy (information from the SAP ALM group) procedure.

Please note that these procedure can be used independently from your BW and Database Version starting from NetWeaver 7.0x

We distinguish between two use cases explained in the FAQ for BW-PCA:

  • Initial copy
    based on an existing original BW system and connected BW source systems


Task Lists - SAP_BW_COPY_INITIAL_PREPARE (SAP BW systems only)
and SAP_BW_BASIS_COPY_INITIAL_CONFIG

Note 2534288 - HEC Service "Homogeneous System Copy / System Refresh (ABAP)
Note 2681701 - System Copy: Task Content (12.1 Improvements)

  • Refresh of an existing system
    based on an existing SAP BW system and connected SAP BW source systems


Task List - SAP_BW_BASIS_COPY_REFRESH_CONFIG

Updating to the minimum level of the mentioned Support Stacks is recommended to minimize the manual effort. For both cases the BW-PCA Task lists support the customer together with the software provisioning manager 1.0 (SWPM) in these software lifecycle management tasks. BW-PCA is embedded in the SAP NetWeaver Landscape Virtualization Management





SAP BW Housekeeping Tasks


Here, you will learn about various housekeeping activities that should be part of the operational concept of your Enterprise Data Warehouse. These housekeeping activities will support you in removing unwanted and unneeded data as well as unused metadata. Scheduling these activities regularly in the system will ensure optimum utilization of system resources while at the same time increasing the overall system performance.
