• What is the cause and solution for SAP error message RSRTS_CDS096 - Nesting of logical operators only supported up to one level ?

  The SAP error message RSRTS_CDS096 indicates that there is an issue with the nesting of logical operators in a calculation view or a query that uses Core Data Services (CDS) in SAP BW or SAP HANA. This error typically arises when you have a complex logical expression that exceeds the allowed nesting level for logical operators (AND, OR, NOT) in the context of the query.
  Cause:
  The error is caused by having more than one level of nested logical operators in your query or calculation view. For example, if you have a condition like this:
  (A AND (B OR C)) OR (D AND E)
  This would be considered too complex and could trigger the error message RSRTS_CDS096.
  Solution:
  To resolve this error, you can simplify the logical expressions in your query or calculation view. Here are some steps you can take:
  
  
  Simplify Conditions: Break down complex conditions into simpler ones. Instead of nesting multiple logical operators, try to flatten the logic where possible.
  
  
  Use Intermediate Calculated Columns: If you have complex logic, consider creating intermediate calculated columns that handle parts of the logic separately. This can help reduce the complexity of the final expression.
  
  
  Review Query Design: Check the design of your query or calculation view. Ensure that you are not unnecessarily complicating the logic. Sometimes, restructuring the query can help avoid deep nesting.
  
  
  Test Incrementally: If you are unsure where the nesting is too deep, test your query incrementally by adding conditions one at a time and checking for the error.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for best practices on writing logical expressions in CDS views.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on best practices for writing logical expressions in CDS views.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  Performance Considerations: Keep in mind that overly complex queries can also impact performance, so simplifying logic not only helps with this error but can also improve query performance.
  
  By following these steps, you should be able to resolve the RSRTS_CDS096 error and create a more efficient and manageable query or calculation view.
