RFC Error message: "functiontemplate from repository was <null>"

[Former Member]

I am getting this error when trying to call my own RFC Function Module:

MP: Exception caught with 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>

I have no idea what is causing this. Can anybody help?

Kind Regards,

Tony.

Tony,

Refer SAP Note: 730870. Q16.

Fyr from SAP Note:

Q 16: While sending a message to the RfcAdapter the error "... functiontemplate from repository was <null>" is shown. Which reasons are possible? 
              A: After receiving a message from the Adapter Engine, the RfcAdapter extracts the payload from the message. Normally this should be an XML document in the RFC-XML format. In this format the root element of the XML document represents the name of the function module and is enclosed in the fixed RFC namespace 'urn:sap-com:document:sap:rfc:functions'. But this only will be checked at a later point, when the conversion from XML to native RFC is done. As prerequisite of this conversion the structures and types of the function module parameters has to be known. This is also called metadata or function template. To get this function template the name of the function module is extracted from the root element of the XML document and is queried against the metadata repository of the communication channel. If the metadata repository doesn't have a function module with this name, the exception named above is thrown. Possible reasons are 
The XML document, which was send to the RfcAdapter, is not a RFC-XML document. So the root element name of this document is not the name of a function module and thus can't be found in the metadata repository.
The metadata repository doesn't contain an entry for this function module name. Normally the metadata repository will be an R/3 system and it's function module repository can be searched with transaction code SE37.

Hi Raj,

Thanks for taking the time to reply. In this case, it seems that the problem was caused by the function module not returning any data. I coorected that and it now works fine.

Kind Regards,
