• What is the cause and solution for SAP error message UJK_EXCEPTION081 - Empty *CASE statement ?

  The SAP error message *UJK_EXCEPTION081: Empty CASE statement** typically occurs in the context of SAP Business Rules Framework or when using ABAP code that involves conditional logic. This error indicates that a CASE statement has been defined without any valid conditions or cases, which leads to an empty evaluation.
  Cause:
  
  Empty CASE Statement: The most direct cause is that the CASE statement is defined without any WHEN clauses or conditions.
  Incorrect Logic: There may be a logical error in the code where the conditions are not properly set up, leading to an empty CASE statement.
  Dynamic Conditions: If the CASE statement is supposed to evaluate dynamic conditions, it might not be receiving the expected input, resulting in no valid cases being defined.
  
  Solution:
  
  Review the CASE Statement: Check the syntax and structure of the CASE statement in your code. Ensure that there are valid WHEN clauses defined.

      " Default action
  ENDCASE.
  
  Add Valid Conditions: If the CASE statement is empty, add the necessary conditions to handle the expected cases.
  Debugging: Use debugging tools to trace the execution flow and see why the CASE statement is not being populated with valid conditions.
  Check Input Values: Ensure that the input values or expressions being evaluated in the CASE statement are correct and not leading to an empty evaluation.
