Data Carrier SAP:SYSTEM not defined Error while attaching document from syclo

Hi,

While I am trying to attach the document from syclo end it's sending an error message data carrier SAP-SYSTEM not defined .but I am able to retrieve and upload the document from DMS end.a

Is any other configuration steps we need to follow for DC20 to store the document from syclo end. we already implemented sap note 2122036  for syclo configuration.

Many Thanks,

Aniruddha
