Purchase Order App - Purchasing Group & Plant

Hi

We have installed and configured S4 HANA with all the FIORI apps enabled. We have a problem with PO creation native app. All the fields are getting filled except the "purchasing group" in header and plant in item. F4 helps comes out empty. I tried debugging the component and leads me no where. Please help.

We have created POs in back end GUI and also with fiori advanced PO creation app without any issue.
