How To Fix 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.
