Why are documents from target version included in CXCK when copying from source to target version?

Hi,

we are using CXCK (Copy Transaction data app) to copy the PL 01 documents from our management accounting version (source) to the statutory version (target). But when posting a PL01 reversing journal in the stat version in month 6 for example and then run CXCK in period 7 from source to target for PL01 with "delete target data first" ticked the system also copies the reversal part of the period 6 journal as a reversing document type hence posting those "COPY" journals indefinitely every time the CXCK is run.

Have you seen this before and how can this be avoided?

PS: we do not have GRCD.

Thanks : )
