Disable message popup in function call

Problem: the function you call issues a message popup window and you want to disable it.

Solution: add EXCEPTIONS section to the function call with exception ERROR_MESSAGE. Like this for example:

CALL FUNCTION 'SOME_FUNCTION'
  EXCEPTIONS
    error_message  = 1.

CALL FUNCTION 'SOME_FUNCTION'
  EXCEPTIONS
    error_message  = 1.
