Hi Gopi,

Why we give 'ok' in that?

ok_code acts just as a temporary variable that stores the value of sy-ucomm.

When user interacts with the screen elements, the function code that you have assigned is filled in the sy-ucomm field which is turn gets reflected in OK_CODE.

want to know all valid screen fields validations?

Field Vaildations can be Done under the PAI event

Ex:

for a group of fields :

CHAIN.

FIELD: ZVXX-event_type,

w_rb1,

w_rb2,

w_rb3.

*Module for validating the IDoc section

MODULE mo_validate_route_1000 ON CHAIN-INPUT.

for a single field :

FIELD vbak-vbeln.

*Check/Populate the field Sales order.

MODULE mo_order_selection.

ENDCHAIN.

Note :

The Field names shld be the same as the name in the Screen.

and the validation against a table can be carried out in the MODULE .
