I have a custom table. FOr the custom table, table maintenance generator is done. Iam calling this custom table from my program using FM : VIEW_MAINTENANCE_CALL.
Now my question is i have few fields in the custom table that should follow the rule like field 1 should always be less than or equal to field 2 on the screen. When user tries to enter a wrong value on the screen it should not allow it.
Can someone help me out where and how to do this validations.
Appreciate and will reward the helpful answers.
