user exit

[former_member188827]

hi all,

i need to validate field xblnr(reference number) for transaction f-28.wen on initial screen after entering xblnr , account etc the user presses enter, the value of xblnr should be checked from a ztable . if the value entered in xblnr exists in ztable the user shuld proceed further otherwise an error message shuld b generated.

cud ny1 suggest me appropriate user exit for this or any other way of doing dis?.

thanxs

Hi,

You can try the exit EXIT_SAPLF048_001. But not sure whether this will satisfy your requirement.
