  The SAP error message CMM_INDEX001 typically indicates an issue related to the assignment of a field symbol in ABAP (Advanced Business Application Programming). This error can occur when there is an attempt to assign a field symbol to a data object that is not compatible or when the field symbol is not properly defined.
  Cause:
  
  Incompatible Data Types: The field symbol may be trying to reference a data object of a different type than what it is defined for.
  Uninitialized Field Symbol: The field symbol may not have been initialized before it is used in an assignment.
  Scope Issues: The field symbol may be out of scope or not accessible in the context where it is being assigned.
  Incorrect Syntax: There may be a syntax error in the code that is causing the assignment to fail.
  
  Solution:
  
  
  Check Data Types: Ensure that the data type of the field symbol matches the data type of the object it is being assigned to. Use the ASSIGN statement correctly to ensure compatibility.
  FIELD-SYMBOLS: <fs_variable> TYPE any.
