BRAIN_DEV656 - Virtual key figure &1 depends on non-matching key figure &2

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN_DEV - BRAIN messages (for use by development)

• Message number: 656

• Message text: Virtual key figure &1 depends on non-matching key figure &2

What causes this issue?

The query contains a virtual key figure, which depends on another key
figure. One of the two key figures is non-cumulative, the other is a
normal cumulative key figure. This is not permitted. Cumulative and
non-cumulative key figures are read separately from each other.
Therefore a user exit cannot combine cumulative and non-cumulative key
figures.

System Response

Query generation is aborted.

How to fix this error?

Split the virtual key figure calculation into a cumulative part and a
non-cumulative part, and combine the two parts using a normal query
formula.

• What is the cause and solution for SAP error message BRAIN_DEV656 - Virtual key figure &1 depends on non-matching key figure &2 ?

  The SAP error message BRAIN_DEV656 indicates that there is a dependency issue between two key figures in a query or a data model. Specifically, it means that a virtual key figure (key figure &1) is dependent on another key figure (key figure &2) that does not match in terms of characteristics or data structure. This can occur in SAP BW (Business Warehouse) or SAP HANA environments when creating or modifying queries in BEx Query Designer or similar tools.
  Cause:
  
  Incompatible Key Figures: The virtual key figure is trying to reference a key figure that has a different set of characteristics or aggregation levels.
  Data Model Issues: The underlying data model may have inconsistencies, such as missing or incorrectly defined characteristics.
  Query Design Errors: The query may have been designed incorrectly, leading to mismatched dependencies between key figures.
  
  Solution:
  
  Check Key Figure Definitions: Review the definitions of both the virtual key figure and the non-matching key figure. Ensure that they are compatible in terms of characteristics and aggregation.
  Adjust Query Design: Modify the query to ensure that the virtual key figure only depends on key figures that have matching characteristics. This may involve changing the logic of the virtual key figure or the key figures it references.
  Recreate Key Figures: If necessary, recreate the key figures to ensure they are defined correctly and consistently.
  Validate Data Model: Ensure that the underlying data model is correctly set up, with all necessary characteristics and key figures properly defined.
  Test Changes: After making adjustments, test the query to ensure that the error is resolved and that the data is being calculated as expected.
  
  Related Information:
  
  Documentation: Refer to SAP Help documentation for detailed information on key figures, virtual key figures, and query design best practices.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  Community Forums: Engage with SAP community forums or support channels for additional insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the BRAIN_DEV656 error and ensure that your key figures are correctly defined and compatible within your SAP environment.
