RS_B4HANA_RC125 - Overview

• Message type: E = Error

• Message class: RS_B4HANA_RC -

• Message number: 125

• Message text: Some queries might behave differently in BW/4 HANA (formula calculation)

What causes this issue?

You have set the 'RSROA_CL_FORM_SWITCH' switch to 'ON'. (For further
information about 'Switch', see SAP Note 2094114.)

System Response

In BW Release 7.50 SP04, the default behavior of 0 * N MIXED = 0 MIXED
has been introduced in formula calculation. Prior to SP04, the result
was 0 * N MIXED = 0.
If the 'RSROA_CL_FORM_SWITCH' switch is set to 'ON', the old behavior is
re-enabled.

RS_B4HANA_RC125 - Details

• The SAP error message RS_B4HANA_RC125 indicates that some queries in SAP BW/4HANA might behave differently due to the way formula calculations are handled in the new environment. This message is a warning rather than a critical error, and it typically arises when transitioning from older versions of SAP BW to BW/4HANA.
  
  Cause:
  The differences in behavior are primarily due to changes in the underlying data processing and calculation logic in BW/4HANA. Some of the key reasons include:
  
  
  New Calculation Engine: BW/4HANA uses a new calculation engine that optimizes performance and leverages the in-memory capabilities of HANA. This can lead to different results for certain calculations, especially those involving complex formulas.
  
  
  Changes in Formula Handling: The way formulas are defined and executed may differ in BW/4HANA compared to previous versions. This can affect how aggregations, exceptions, and conditions are processed.
  
  
  Data Model Changes: The transition to BW/4HANA often involves changes in the data model, which can
