Software Logistics (SL) for SAP BW and BW/4HANA

Blog Content

Here is my current Blog collection about “where the cool stuff happens …”

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

Blog: System Copy Automation for SAP Business Warehouse System Landscapes
Blog: New Note Analyzer for SAP BW PCA and Housekeeping

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.

Note 1855296 – BW Housekeeping, Upgrade and Migration Task List Improvements 1
Note 2124850 – Class CL_RSO_DTP_ERROR_LOG_DELETE is missing Housekeeping task list
Note 2407784 – How to clean up RSBKDATA and related tables

The Housekeeping Task List (Pre/Post Steps) allows you to automate mandatory tasks prior to upgrade/migration with DMO to ensure the quality of the migration process and the health of your BW System.

      Thanks Roland, its very useful info.

      We are planning to upgrade our BW system from 7.4 to 7.5 on HANA. For that we are looking for general BW 7.5 upgradation Checklist like Pre-upgrade BW activity and post-upgrade BW activity. More interested in Related to BW activity not basis activity.

      Do you have any Checklist for BW activity?

      Thanks

      We are interested in deploying our existing BPC 10.1 / BW 7.4 application to Azure cloud. Noticed first guidance on SAP BW4/HANA on Azure. Is an upgrade roadmap from BPC10.1 / BW7.4 to BPC11 / BW7.5 available on Azure? Our goal on BPC11 is to go back to the embedded model.

      Hello John

      actually there is no Upgrade from  BPC10.1 / BW7.4 as it would be a so called "In-Place Conversion via an Upgrade to "BW on HANA 7.50".

      For the Upgrade to SAP BW 7.50 see the following Presentation

      Then you can convert to BW/4 and BPC 11.0 according to the Blog - On the Road to BW/4HANA – first stage accomplished – second stage finalized – choose your Path

      As you already mentioned the SAP First Guidance – deploy SAP BW/4HANA in the Azure Cloud
      there is no difference between the on-premise Deployment and the IaaS Deployment on Azure

      Best Regards Roland

      Hello Experts,

      Finally our company decided to move our database do HANA.

       

      We are currently in SAP BW 731 and we also use BI-IP capabilities.

       

      When moving to BW on HANA the BI-IP capabilities will be affected? Do we need to activate anything to continue using BI-IP? Aditional licenses are necessary?

       

      Many thanks for your help.

       

      Best Regards,

       

      Rui

      Hello Rui

      You can still use BI-IP with BW on HANA

      With BW/4 you have to purchase the BPC Add-On to access the former BI-IP Application/Data again

      Hi

      technically yes. Furthermore I would use separate HANA Instances for S/4 and BW/4 and not a single multi-tenant instance

      best regards roland

      Good day!

      Does any similar SAP_BW_HOUSEKEEPING task list exist for BW/4HANA? Only 7.5* mentioned in related notes.
