When trying to set up RFC connection in SAP ERP to connect to SAP MII we get an error that the registry entry for the program ID is missing. It sounds like 'Program ID is not registered'.
When we try to set up the IDOC listener in MII and enter the program ID and save, the listener saves successfully and no error message is triggered. It is also in green color. But when trying to use it in SAP it gives error. I think that the program ID did not get registered by the steps we followed in MII. Could this be an authorization issue? Any other configuration that could be missing?
PS: I followed all steps of the document: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a02bc706-15f2-2c10-1aab-a1927ada11f0?quicklink=index&overridelayout=true
Any pointers would be appreciated.
