Hi ,

You can use the event at selection-screen on field_name.

since your field in selection screen is vdrcsg (the parameter name)

so the statement would be

AT SELECTION-SCREEN ON vdrcsg.

select *  from lfa1
where lifnr = vdrcsg.
if sy-subrc <> 0.
"error message.
endif.

Similarly write the code for tour storage location , comparing the entered value with values in table T001L.
