How do i provide a value help(F4) to a standard DB table field?

Hi,

I need to provide an F4 help to the field PRPS-PSPNR.I do not have the <b>access key</b> to assign the search help that i create to the table field.

A collective search help <b>PRPM</b> exists that displays four columns.I need to display only two of those - WBS elements and its description.

Could you please help me out ASAP.

Regards,

Monica.
