Modify entries of Value mapping table fromValue mapping replication

Hi,

I have successful uploaded value mapping table from external source(SAP Table) using value mapping replication. The entries are displayed in the cache monitoring.

Now what should i do,if i have to modify the entries in the value mapping table.I tried uploading the new entries using the same GUID, Agency, Schema.... but now both the previously uploaded and the new entries are dispalyed in Cache monitoring.

But i want only the new entries to get reflected in the value mapping table. So kindly request anyone to help.

Regards,

Anup
