These events provide developers with hooks to add custom logic or validations to the standard table maintenance process without modifying the generated code. Some common TMG events in SAP ABAP include: BEFORE OUTPUT: This event is triggered before the maintenance screen is displayed. Developers can use this event to modify the screen layout or initialize screen fields. AFTER INPUT: This event is triggered after the user enters data on the maintenance screen and clicks the save button. Developers can ...
