Error in system E04CLNT100 while copying the document

Hi all,

I am involved in a SAP social service service implementation where both CRM and PSCD(ECC) is being used. We were able to configure the details so that SXP, GED and GPD are getting created in ECC. But somehow the NCD are not generating. While saving the SSP in CRM the below error messages are coming.

E04CLNT100 is the ECC system details.

Any suggestion / details on this respect will be helpful.

Thanks,

Sid
