Hi,

Can someone tell me how to add an F4 help to an editable field in ALV Grid(editable)...I tried giving the field in the fieldcatalog for F4 help as X and the dropdown button appeared, but the values are not getting displayed. IS there anything else i need to do to get this done.

Thnx.

if you are not using the data element for the field 'F4' help won't come. in this situation, use the ONF4 event to build the F4 Help.
