• What is the cause and solution for SAP error message RSPLS_CR091 - Sources &1 and &2 are contained in key part and data part respectively ?

  The SAP error message RSPLS_CR091 indicates that there is a mismatch between the key part and the data part of a query or InfoProvider in SAP BW (Business Warehouse). Specifically, it suggests that the sources specified in the query are not aligned correctly, meaning that one source is in the key part while the other is in the data part.
  Cause:
  
  Key Part and Data Part Mismatch: The error typically arises when the query is trying to access data from two different sources where one is defined in the key part (which usually contains the characteristics) and the other in the data part (which contains the measures or facts).
  Incorrect Query Design: The query may have been designed incorrectly, leading to a situation where the key figures and characteristics are not properly aligned.
  Data Model Issues: There may be issues with the underlying data model, such as missing or incorrectly defined relationships between the key figures and characteristics.
  
  Solution:
  
  Check Query Design: Review the query design in the Query Designer. Ensure that the characteristics and key figures are correctly defined and that they belong to the same InfoProvider or are compatible.
  Align Key and Data Parts: Make sure that the sources used in the key part and data part of the query are compatible. If necessary, adjust the query to ensure that both parts reference the same InfoProvider or compatible sources.
  Review InfoProvider Structure: Check the structure of the InfoProvider to ensure that the key figures and characteristics are correctly defined and that there are no missing links or relationships.
  Test with Simplified Query: If the issue persists, try creating a simplified version of the query to isolate the problem. Start with a basic selection of key figures and characteristics and gradually add complexity to identify where the mismatch occurs.
  Consult Documentation: Refer to SAP documentation or support resources for additional guidance on query design and troubleshooting.
