We have two synchronization process QC1-QC2 and QC2-Change Synergy. A set of records in QC1 should not be modified by any means thru synchronizer/backend query. If it is changed in any other end, QC2 or Change synergy, it should not be considered during QC1-QC2 synchronization.

Could anybody help in this regard?

The QC version is QC10 everywhere.
