Triggering Controlled Terminations 

Use

In user exits and the form routines of a form class, exception situations can occur where the system is to react with a controlled termination. The print process is not to be terminated, only the printing of the current document. To make sure that terminations that disrupt the print process of the Print Workbench do not occur, you can use the ABAP macro MAC_PRINT_CANCEL to define how the termination is to take place.

Procedure

Always use the ABAP macro MAC_PRINT_CANCEL in all user exits (see Controlled Terminations in Exception Situations).
