Assume that you use a WCF-SAP adapter, and you set the ConnectorType value to NCo and you set a specific RFC Server Destination Name. When the saprfc.ini file contains extra comments, spaces, and carriage returns within the destination definitions, the WCF-SAP adapter fails and you receive the following error message:

The Messaging Engine failed to add a receive location "MyReceiveLocation" with URL "sap://CLIENT=###;LANG=EN;@a/sapserver/##?ListenerDest=DEST1&RfcSdkTrace=False&AbapDebug=False" to the adapter "WCF-SAP".
