This error indicates that the CASE statement is not properly terminated or that there is a missing or incorrect statement at the end of one of the branches.
  Cause:
  
  Missing ENDCASE Statement: The most common cause is that the ENDCASE statement is missing for the CASE structure.
  Incorrect Syntax: There may be a syntax error within the CASE branches, such as missing statements or incorrect formatting.
  Unreachable Code: If there is code after the ENDCASE that is not properly structured, it can lead to this error.

  Check for ENDCASE: Ensure that every CASE statement has a corresponding ENDCASE statement.

  Example:
  Here’s a simple example of a correct CASE statement in ABAP:
  DATA: lv_value TYPE i.
  
  CASE lv_value.
