• What is the cause and solution for SAP error message RSRTS_CDS155 - CAST (&1) only evaluated for label (formula annotation available) ?

  The SAP error message RSRTS_CDS155 typically occurs in the context of SAP BW (Business Warehouse) when working with Composite Data Sources (CDS) views and involves issues related to the evaluation of a formula or calculation in a query. The message indicates that the system is unable to evaluate a certain expression or formula due to the way it is defined or the context in which it is being used.
  Cause:
  
  Formula Annotation Issues: The error suggests that the formula annotation is not being properly recognized or evaluated. This can happen if the formula is not correctly defined in the CDS view or if there are issues with the underlying data model.
  Data Type Mismatch: The error may also arise from a mismatch in data types when trying to cast a value. If the data type of the source does not match the expected type in the formula, it can lead to evaluation issues.
  Contextual Limitations: The context in which the formula is being evaluated may not support the operations being performed, leading to the error.
  
  Solution:
  
  Check Formula Definition: Review the formula annotations in your CDS view. Ensure that they are correctly defined and that all necessary fields are included.
  Data Type Validation: Verify that the data types of the fields being used in the formula match the expected types. If there are any discrepancies, adjust the data types accordingly.
  Simplify the Formula: If the formula is complex, try simplifying it to isolate the issue. This can help identify which part of the formula is causing the problem.
  Debugging: Use debugging tools in SAP to trace the execution of the query and identify where the evaluation fails. This can provide insights into the specific conditions leading to the error.
