Custom F4

Hi Gurus,

I have created a custom screen that will enter values for Z_LIFNR. However the requirement now is instead of displaying the Vendor No. (Z_LIFNR) I have to display the Vendor Name (Z_NAME1), If I do this so the value in the screen field will take name and passes it on in PAI of the screen, which I don't want.

To make it simple I want the F4 to return the Name of the Vendor in screen field but when passing to the PAI I want the Vendor No. to be passed to the processes not the displayed Name.

How can I do that?

Regards.
