Hi,

What is your Actual Requirement. you can do validations in selection screens also.

your are asking Warning and Error message, actually which message you want to through, why becuase if you use Error message it won't move to next field until it corrected and Waring message will give when you press enter it will moves to next step. now you can decide which message type you want

1. My point is if you don't want blank fields then that field should make it as Obligatory field then it never move without value to next field or Default value you can initialize.

2. you can put search help to that field then user selects maximum from that data only or at selection-screen on field use the event and do validation there

if sy-subrc ne 0 through a error message
