delete pnp fields in program when using PNP LDB

Hi all,

this is naresh.

i have a selection-screen with two fields PERNR and WERKS.

those fields are custom one.

but i am using PNP LDB and GET PERNR event.

issue is i am entering WERKS, but not PERNR.

so when GET PERNR event is trigerred all the pernr and werks will be retrived from DB.

before get PERNR, i have to pass the entered values to the PNP LDB.

so i should delete entire PERNR and WERKS.

and append entered values.

i have used delete query.

it is not working.

can any1 tell solution for this?

thanks,

naresh.
