• What is the cause and solution for SAP error message CM_EHENV_CDEF018 - Recurrence detected: chosen data source for variable "&2" points to "&1" ?

  The SAP error message CM_EHENV_CDEF018 indicates that there is a recurrence detected in the data source configuration for a variable in your SAP system. This typically occurs when a variable is set to reference itself or when there is a circular reference in the data source definitions.
  Cause:
  
  Circular Reference: The variable is configured in such a way that it points back to itself or to another variable that eventually points back to it.
  Incorrect Data Source Configuration: The data source for the variable may not be set up correctly, leading to a situation where the system cannot resolve the variable's value.
  Hierarchy Issues: If the variable is part of a hierarchy, there may be a misconfiguration that causes it to reference itself.
  
  Solution:
  
  Review Variable Configuration: Check the configuration of the variable in the SAP system. Ensure that it does not reference itself or create a circular dependency with other variables.
  Adjust Data Source: Modify the data source for the variable to point to a valid and non-recursive source. Ensure that the data source is correctly defined and does not lead to circular references.
  Test Changes: After making adjustments, test the variable to ensure that it resolves correctly without triggering the error.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring variables and data sources to avoid circular references.
