Webservice Error in Updating Contact

Hi Experts,

When I want to update contact person through PI using the interface "Replicate Business Partner from SAP BusinessSuite", I get the error  "Update not possible; existing data for BUSINESS_PARTNER not fully specified".

As shown below ,  I'm passing the C4C Contact number in INTERNALID and RECEIVERINTERNALID with actioncode as '02' along with the value in custom field "TRIPOLISID" which needs to be updated.

Message from PI to Update Contact

PS: I know that there is "Manage Contact" Synchronous service to update CONTACTS in C4C but because of the PI interface dependencies , we cannot use a Synchronous service to update CONTACTS .

Thanks in advance.
