If you are using a selection-screen....

at selection-screen.

if p_field is initial.
message e001(00) with 'Hey, fill in this field'.
endif.

If you are using a dynpro, then its pretty much the same. Add a MODULE in your flow logic.

FIELD P_FIELD MODULE_CHECK_PFIELD.

In you ABAP program, do something like this.

MODULE_CHECK_PFIELD.

if p_field is initial.
message e001(00) with 'Hey, fill in this field'.
endif.

ENDMODULE.

Hi,

A little more:

You can also use this so that the cursor stays on p_field field on the scree.

at selection-screen on p_field.

if p_field is initial.

message e001(00) with 'Hey, fill in this field'.

endif.

Hi Rad,

If it is already a required field, then why do we need to handle this separately. Required fields have this property already embedded in SAP.

If the user doesn't enter a value, then SAP throws an error.

However, whatver fellow sdn members suggested is equally valid for all the fields(mandatory or otherwise).
