• What is the cause and solution for SAP error message ACM353 - This CTE expression was already checked before within this role ?

  The SAP error message ACM353, which states "This CTE expression was already checked before within this role," typically occurs in the context of SAP Analytics Cloud (SAC) or SAP BusinessObjects when dealing with calculated measures or expressions in a model or report. This error indicates that the system has detected a duplicate check of a Common Table Expression (CTE) within the same role, which is not allowed.
  Cause:
  
  Duplicate CTE Definition: The error is often caused by defining the same CTE expression multiple times within the same role or context. The system is designed to prevent redundant checks for performance and logical consistency.
  Modeling Issues: It may arise from how the model is structured, particularly if there are overlapping or conflicting definitions of measures or dimensions.
  Role Configuration: The role in which the CTE is being checked may have been configured incorrectly, leading to the same expression being evaluated multiple times.
  
  Solution:
  
  Review CTE Definitions: Check the definitions of your CTE expressions within the role. Ensure that each CTE is defined only once and that there are no duplicates.
  Refactor Expressions: If you find that the same logic is being used in multiple places, consider refactoring your expressions to avoid redundancy. You can create a single CTE and reference it where needed.
  Check Role Settings: Review the role settings and ensure that there are no conflicting definitions or configurations that could lead to this error.
  Testing: After making changes, test the model or report to ensure that the error no longer occurs and that the expected results are produced.
  
  Related Information:
