T_Code 1KEK - Transferring Receivables and Paybles to PCA

Hi SAPients,

We normally do the transfer of Receivables and Paybles to PCA through T-code 1KEK as a period end closing process. Now something strange is happening which was never before. While transferring the Receivables and Paybles through 1KEK, all the line items are getting transferred to Dummy profit Centre rather the respective ones which is resulting in the mismatch in basic ledger and comparision ledger in T-code GCAC ( Ledger Comparision ). Can any body explain why it is happening and where the dummy profit centre is getting picked from for 1KEK?

Thanks,

BABA
