• What is the cause and solution for SAP error message RDB_REC302 - Key figure & is not a single record key figure ?

  The SAP error message RDB_REC302 indicates that there is an issue with a key figure in a report or query. Specifically, it means that the key figure you are trying to use is not defined as a single record key figure, which is required for certain operations in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  
  Key Figure Definition: The key figure in question is likely defined in a way that allows for multiple records (e.g., it may be an aggregated or calculated key figure) rather than a single record key figure.
  Query Design: The query or report you are trying to execute may be expecting a single record key figure, but the key figure you are using does not meet this requirement.
  Data Model Issues: There may be issues with the underlying data model or InfoProvider that is causing the key figure to behave unexpectedly.
  
  Solution:
  
  
  Check Key Figure Definition:
  
  Go to the InfoObject definition in the SAP BW system and check the properties of the key figure. Ensure that it is defined as a single record key figure if that is what your query requires.
  If it is not, you may need to create a new key figure that meets the requirements or adjust the existing one.
  
  
  
  Modify the Query:
  
  If the key figure is correctly defined but the query is still failing, consider modifying the query to use a different key figure that is defined as a single record key figure.
  Review the query structure and ensure that it aligns with the data model and key figure definitions.
  
  
  
  Data Model Review:
  
  Review the underlying data model (e.g., InfoCube, DataStore Object) to ensure that it is set up correctly and that the key figures are being populated as expected.
  Check for any transformations or data loading issues that might affect the key figure.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on key figure definitions and query design best practices.
  
  
  
  Testing:
  
  After making changes, test the query again to ensure that the error is resolved.
  
  
  
  Related Information:

  SAP Notes and Community: Check SAP Notes for any known issues or patches related to this error message, and consider reaching out to the SAP Community for additional support.
