  The SAP error message RSRTS_CDS036 Unsupported path expression (at &1) typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with Core Data Services (CDS) views or when executing queries in the SAP BW Query Designer. This error indicates that there is an issue with the path expression used in the CDS view or query definition.
  Cause:

  Data Model Changes: If there have been changes to the underlying data model (e.g., changes in the structure of the CDS view or the underlying tables), it may lead to unsupported path expressions.
  Incompatible Data Types: The data types of the fields being referenced may not be compatible, leading to issues in the path expression.

  Solution:
  
  Check Path Expressions: Review the path expressions used in the CDS view or query. Ensure that they are correctly defined and reference valid fields or entities.
  Validate Data Model: If there have been recent changes to the data model, ensure that the CDS view or query is updated accordingly. Check for any changes in the underlying tables or structures.
  Use Compatible Data Types: Ensure that the data types of the fields being referenced in the path expression are compatible. If necessary, perform type conversions.
  Test Query in Query Designer: If you are using the Query Designer, test the query step by step to identify where the error occurs. This can help isolate the problematic path expression.
