This issue occurs when you use a WCF-SAP NCO adapter in BizTalk Server. For example:
When you call BAPI_SALESORDER_GETLIST, the response is identical when orders are found. For a scenario in which no orders are found, if you use the ClassicRFC library, there is no record in the output. This is correct. However, when you use the WCF-SAP NCO adapter, you may see a record in the output that resembles the following :
<SALES_ORDERS> <BAPIORDERS xmlns="<Placeholder>"/> </SALES_ORDERS>
