I am new to webdynpro and asked to rectify some issues in a webdynpro application on. The Scenario is like this, I have a purchase order and I want to get line item details through a webdynpro page. I am using a BAPI, BAPI_PO_GETDETAIL to get relevant details in the purchase order. BAPI_PO_GETDETAIL is modified to include two more Z Fields in PO_Header to get Vat number & Payment Text. When I executed the BAPI in an R/3 system for a particular PO I am able to see those two Z fields are getting populated with data. Now, I need to replace an existing SAP Webdynpro field with my Z field through NWDS. Please let me know the procedure step by step to include those two fields in place of an existing SAP Standard field in Webdynpro application.
Thanks in advance,
With Best Regds,
