Dear All,

I am Devesh Kapse, SAP BW on HANA consultant at Accenture Solutions. I have worked with SAP BW and BW on HANA implementation, BW and ECC upgrades, S/4 HANA migration, BI ABAP and BO tools.

This Blog is my learning from a S4 HANA migration project where I was responsible for delivery(Adjustment of BW w.r.t. S4 migration & Quality) of BW on HANA 740 system and SLT after migration. I could find very minimal knowledge on the impacted extractors with S4 HANA over the internet and Hence sharing the the learning.

What is the impact of Standard BW extractor with S/4 HANA implementation or ECC to S4 migration?

Wondering on the above question. So here is some learning I had from my last project.

  1. Before starting the S4 migration, Check the SAP note – 2500202 – S4TWL – BW Extractors in SAP S4 HANA. The note contains the list of BW extractors which are fully supported, Partially supported and obsolete with S/4 HANA. For example Finance data extractor 0FI_GL_10 is Whitelisted with S/4 HANA, this means the data source is fully supported and will work with out any restriction. 0COSTELMNT_ATTR is Not whitelisted, will work but with some restrictions. 0CO_OM_ABC_1 is Not Whitelisted and DS not working – no alternative exists.2LIS_01_S001 is deprecated.
  2. Before migration Check the underlying tables for the BW data sources, as there are many application (Transparent) tables which are now Views, and for many tables the keys are changed. This may effect the data loads at DSO level and may give you wrong information. for example – the source table FAGLFLEXT, for data source 3FI_GL_L1_TT, is a DB view with S4 with all fields as keys. There may be a situation where at the DSO level, due to changes in Keys, we may not get the unique record or records might over right, resulting in mismatch in totals.

 

The next Blog will be following –

  1. SLT Upgrade methods.
  2. Extraction of S4 CDS views with BW on HANA 740 systems.

Thanks and Regards,

Devesh

    Hi Devesh,

    Nice information..we are also migrating  HANA ECC  to S/4 HANA with BW 7.5 HANA system,initially

    they run on report in that report for BW part  Data sources categorized ” DS Working -No Restrictions and “DS not working -no Alternative exits “.

    In the category “DS not working -no Alternative exits ” we got only generic data sources ..so how can we proceed on this?? any idea….

    Hi Sairam,

    SAP is working on the same and will provide the standard ABAP CDS views for the same which can be consumed in to BW/4 HANA system directly.

    Till the time, if really urgent, you can go with custom CDS views, Not the traditional way as CDS view will be the future way of extracting data.

    Thanks, Devesh

    Hi Devesh,

    Thank you for taking the time to write about your experience of impact on BW extractors, while migrating to S/4 HANA.

    We are doing a assessment for a customer, who intends to move to S/4 HANA from ECC EHP 5.

    We have referred to the SAP Note 2500202, mentioned by you in your blog. However there are approximately 133 extractors for EHS, which are part of the cusomers system and are not covered by the above mentioned note. We are therefore unable to understand the impact on these BW extractors (for EHS related data) on moving to S/4 HANA.

    The BW system is on oracle database.

    Mentioned below are some of the extractors out of the 133, which are not covered as part of the above mentioned note. Can you please point us in the right direction, from where we can get this information?

    1CL_OCON001
    1CL_OMAT001
    1CL_OPM_001
    1CL_OWBS001
    0EH_ACTCAT_TEXT
    0EH_ACTNAT_TEXT
    0EH_INCSTAT_TEXT

    Thanks in advance.

    Jayesh
