Additional Check for Existing View
An additional check which is called directly after input into fields and sends a message if necessary is to be added to the view of another application.
Action required:
Define application if you have not already done so (see Basic Settings , Applications).
Assign the application to the object part if the application object uses divisibility and the application is not yet assigned (see Divisibility )
Implement the check function module in its own function group
Store the name of the function module in the view definition in the subnode
Additional checks
(see Screen Layout , Field Groups.)
Note:
Do NOT store the name of your check function module directly in the
After input
field in the view definition if this view belongs to another application. If you were to do this, it would change the table entry of the other application. The change could then be lost during an upgrade.
