Hello Experts,
When a customer clicks F4 on a field in VA01, for example, "Ship-To Party", he gets a pop-up screen directly "Cust. search using addr. attrb." (Fig. 1) where he can enter details to filter input data.

Another customer while pressing F4 for drop-down for same field "Ship-To Party" he does not get of "Cust. search using addr. attrb." pop-up screen (Fig. 1) where he is forced to click the small icon "Display All values" (Fig. 2) and only then he is getting the "Cust. search using addr. attrb." pop-up (Fig. 1).
Where can I change the lay-out/display setting so that F4 drop-down directly brings up the "Cust. search using addr. attrb." pop-up window (Fig. 1)?

Thank you very much.

Sujit K Banerjee.
