• What is the cause and solution for SAP error message DDLS380 - The current expression is not supported in SEARCHED CASE after THEN ?

  The SAP error message DDLS380 indicates that there is an issue with the syntax of a SQL statement, specifically in the context of a SEARCHED CASE expression. This error typically arises when the expression used after the THEN keyword in a CASE statement is not valid or not supported.
  Cause:
  The error occurs when:
  
  The expression following the THEN keyword is not a valid expression for the context.
  There may be a syntax error or a type mismatch in the expression.
  The SQL statement is not properly structured according to the SQL syntax rules.
  
  Solution:
  To resolve the DDLS380 error, you can take the following steps:
  
  
  Check Syntax: Ensure that the syntax of your CASE statement is correct. A typical SEARCHED CASE structure looks like this:
  CASE
      WHEN condition1 THEN result1
      WHEN condition2 THEN result2
      ...
      ELSE default_result
  END
  
  
  Validate Expressions: Make sure that the expressions used in the THEN clauses are valid and compatible with the expected data types. For example, if the CASE statement is expected to return an integer, ensure that all THEN results are integers.
  
  
  Use Simple CASE if Applicable: If your logic allows, consider using a SIMPLE CASE statement instead, which is structured differently and may avoid the issue:
  CASE expression
      WHEN value1 THEN result1
      WHEN value2 THEN result2
      ...
      ELSE default_result
  END
  
  
  Review Documentation: Consult the SAP documentation or SQL reference for the specific version you are using to ensure that you are following the correct syntax and rules for CASE statements.
  
  
  Test in Isolation: If possible, isolate the CASE statement and test it independently to identify the specific part of the expression causing the error.
