Currently we use Enterprise SAP R/3 adapters to communciate with SAP R/3 4.6. SAP r/3 upgrade to 5.0 is being talked about. Has anyone used Enterprise SAP Adapters with R/3 5.0. Any issues or known impact.

Thanks

Folks,

Tried connecting Enterprise SAP Adapter version 4.2 with JcO 2.0.8. to SAP ECC 5.0. At this point receiving Standard SAP Idocs from SAP into webM is a big issue. Get the following error :

Run-time exception while processing “DeliveryDocumentRecDELVRY03”

com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: connection closed without message (CM_NO_DATA_RECEIVED) com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: connection closed without message (CM_NO_DATA_RECEIVED) 

at com.sap.mw.jco.rfc.MiddlewareRFC$Client.nativeReset(Native Method) 

The configured operation does not recognize this Idoc. So for e.g. when we enter the Idoc Type, Msg Type and extension, for an ALE Inbound operation, we get the same error as above.

We tried upgrading jco version to 2.16 or 2.12 but the ES SAp adapter wont even start. We are running adk version 4.2.1.

Any help is appreciated.

Thanks

Did you check if the IDoc has changed between 4.6 to 5.0 ? During SAP upgrades, IDoc or BAPIs might have changes that need to be updated in wm Adapter.
