• What is the cause and solution for SAP error message RSRTS_CDS123 - Derivation of &1 leads to circular dependence (via &2) ?

  The SAP error message RSRTS_CDS123 indicates that there is a circular dependency in the derivation of a calculation view or a CDS (Core Data Services) view. This typically occurs when a data source or a calculation view references itself directly or indirectly, creating a loop that the system cannot resolve.
  Cause:
  
  Circular Reference: The most common cause is that the calculation view or CDS view is referencing itself or another view that eventually references back to it.
  Incorrect Joins: Joins between tables or views that create a loop can also lead to this error.
  Derived Attributes: If derived attributes in a view reference each other in a way that creates a circular dependency, this error can occur.
  
  Solution:
  
  Review Dependencies: Check the dependencies of the calculation view or CDS view. Ensure that no view is referencing itself directly or indirectly.
  Refactor Views: If you find circular references, consider refactoring your views. This may involve breaking down complex views into simpler components or changing the way views are joined.
  Use Alternative Logic: If possible, use alternative logic to achieve the same result without creating circular dependencies. This might involve using different calculations or aggregations.
  Check Derived Attributes: If you have derived attributes, ensure that they do not reference each other in a way that creates a loop.
  Testing: After making changes, test the views to ensure that the error is resolved and that the data is being returned as expected.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on calculation views and CDS views, as well as best practices for avoiding circular dependencies.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  Debugging Tools: Use SAP's debugging tools to trace the execution of the views and identify where the circular reference is occurring.
  
  By carefully analyzing the structure of your views and their relationships, you can resolve the circular dependency and eliminate the RSRTS_CDS123 error.
