Hi Babu,
I am facing the same error. I created a TASKPROCESSING service and assigned the Software version as DEFAULT and then changed it to /IWPGW/BWF.
However, i could not find this node in spro.
SPRO->SAP Netweaver->Gateway->OData Channel Development with IW_BEP->Registration->Assign Data Provider to Data Model.
Is this changed in the later released?
Thanks,
Pratheep
