Hi,

You need use the START-OF-SELECTION, then it will back to the selection screen. you are doing all the code in AT SELECTION-SCREEN, so it won't display the Selection screen when you press Back button,

Hello,

Insted of using leave to list-processing, use LEAVE TO LIST-PROCESSING AND RETURN TO SCREEN "ur screen number"

BDC performing should be in Start of selection event.

change the code like this and see

PARAMETERS : KANID TYPE PKPS-PKKEY.

AT SELECTION-SCREEN.

CTUMODE = 'N'.

CUPDATE = 'S'.

AT SELECTION-SCREEN OUTPUT.

KANID = ''.

START-OF-SELECTION.

PERFORM BDC_DYNPRO USING 'SAPLMPKP' '0301'.

PERFORM BDC_FIELD USING 'BDC_CURSOR'

'RMPKB-PKKEY'.

Reward points if useful
