Problem with Bapi_po_Getdetail return values

Question

We have developed a web service in asp.net to get the details of a particular purchase order number calling Bapi_po_Getdetail. The input parameters that we pass are:
string  ITEMS = “X”
string PURCHASEORDER= “<purchase order number>”
But when we debug and check the return values from the bapi, BAPIEKPO Table doesn’t have any data, it is null.
Could someone help us, please?

Answer 1

Please initialize the BAPIEKPOTable bedore call. Passing null allways returns null.
NCo:
string ITEMS = “X”
string PURCHASEORDER= “<purchase order number>”
BAPIEKPOTable result = new BAPIEKPOTable();
proxy.Bapi_po_Getdetail(ITEMS, PURCHASEORDER, ref result);
Soap Processor / Web Service Wizard
string ITEMS = “X”
string PURCHASEORDER= “<purchase order number>”
BAPIEKPO[] result = new BAPIEKPO[0];
proxy.Bapi_po_Getdetail(ITEMS, PURCHASEORDER, ref result);
