FS-CD: Error in Transafer of Posting from FSCD in to Main Ledger

Hi,

I have posted an entry in FSCD (Insurance, sub ledger) on 01.05.2009 and wanted it to transfer in to main general ledger. Now I get the following error message:

Reconciliation Key: FG2009050102

Co.Code: 1000

Status of Recon. Key: Error in RWIN-Interface

Error detail: Create an account 12345678 on 01.05.2009 as a cost element in controlling area SGAP

Message ID: KI

I have the same parameters maintained for this account in the both ledgers "sub ledger" as well as "main general ledger".

Can anybody tell me which changes should I do in FS-CD and how?

Thanks

SIM
