Hi,

In the Module Pool Program you can you the screen numbers till 9000. Screen numbers greater than 9000 are reserved by SAP for SAP System Customers.

Also the Screen numbers from 1000 to 1010 are reserved for the maintainence for ABAP Dictionary Screens.

FIELD F1 MODULE M1 ON INPUT.

If you use the ON Input addition in a MODULE Statement after FIELD, the MODULE is only called if the field contents have changed their initial values.

FIELD F2 MODULE M2 ON REQUEST.

If you use the ON REQUEST addition in a FIELD Statement, the MODULE is called only if the user enters a new value in the field.

Thanks and Regards,

Samantak.
