  The SAP error message RSFBP122 indicates that there is an issue with a compounded field in a key field definition within a data model or a query. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with InfoObjects, queries, or data models.
  Cause:
  The error occurs when:
  
  A compounded field is being used incorrectly in a context where a key field is expected.
  The compounded field is not defined as a key field in the relevant InfoObject or data model.
  There may be a mismatch in the configuration of the InfoObject or the query definition.
  
  Solution:
  To resolve the RSFBP122 error, you can follow these steps:
  
  
  Check InfoObject Definition:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1).
  Verify that the compounded field is correctly defined and that it is set up as a key field if it is intended to be used as such.
  
  
  
  Review Query Definition:
  
  If the error occurs in a query, check the query definition in the Query Designer.

  Adjust Compounded Field Usage:
  
  If the compounded field is not meant to be a key field, consider using the individual components of the compounded field instead.
  If necessary, redefine the compounded field or create a new InfoObject that meets the requirements.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no dependencies or references to the compounded field that could be causing the issue.
