How to display an error message in maintenace view


I have following requirement.

I have a table. In the table, there is a field named REPORT which keeps an executable report name. When adding an entry i need to fill the field with an report name, which should exist in the system. The report name should not be include objects.

Then I use search help HELP_TRDIR with import parameter SUBC = 1. I also create a maintenance view for the table.

Then my question is how to display a warning message if the report I input in REPORT field doesn't exist in the system. If I need to modify the generated objects of the maintenance view, how to do it.

The reason i don't use foreign key is that it seems filter functionality is not availabe in the case with import parameter SUBC = 1.

Thanks in advance,

Best Regards, Johnney.

You need to add your validation in the table maintenance events:

Use the event : 01 - Before saving data to the databse table... for this purpose

1) Go to Menu-> Utilities->Table mainatenace generator

2) On the table maintenance screen->Menu->Enviroement-> Modifications->Events

3) select an event 01 and give some subroutine/form name.

4) Add your validation in the form(Note this form should be in the Func Group of the table maintanance genetaor)
