Problem calling communication channel

[Former Member]

Hi All

I created a scenario where idoc is send from ecc with idoc adpter then to value mapping with user defined function to get a value stored in the db. When I test the mapping it gives me error:

Errorcom.sap.aii.mapping.lookup.LookupException: Plain exception:Problem when calling an adapter by using communication channel CC_UDF_RECEIVER (Party: , Service: metsapxd, Object ID: 920cddf81b013e8db6056cc14cafc5a3) Check whether the communication channel exists in the Integration Directory; also check the cache notifications for the instance Integration Server (central Adapter-Engine) Channel object with Id Channel:920cddf81b013e8db6056cc14cafc5a3 not available in CPA Cache. com.sap.aii.mapping.lookup.LookupException: Problem when calling an adapter by using communication channel CC_UDF_RECEIVER (Party: , Service: metsapxd, Object ID: 920cddf81b013e8db6056cc14cafc5a3) Check whether the communication channel exists in the Integration Directory; also check the cache notifications for the instance Integration Server (central Adapter-Engine) Channel object with Id Channel:920cddf81b013e8db6056cc14cafc5a3 not available in CPA Cache.

When I go to runtime workbench and check communication channel monitoring the light is green but with error underneath:

Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: functiontemplate from repository was <null>: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: functiontemplate from repository was <null>

Error in processing caused by: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: functiontemplate from repository was <null>

Deletet the scenario and created it again but stil gives same errors?

Can the lookup table be in xi or should it be in ecc system?

Any help will be appreciated.

Hi

Thx for the Reply. Can the rfc lookup be in the xi abap site or should it go to the ecc system?

[prateek]

Theroetically the RFC could be created on XI abap stack. But a usual practice is to use one on the ECC system. U may consider value mapping too if it suits ur scenario.

HI Stephan,

Make sure that the communication channel CC_UDF_RECEIVER is created at ID and is activate. The important point to notice here is that this CC should be under the WebAs ABAP Business System for the R3 system at which you are trying to make the lookup.
