SS2K5 dynamic replication

Hi

I have 'aTable' table on both dbMaster and dbSlave databases... The structure of aTable is
id(int),name(vchar),price(int)cantity(int),global(bit)

If Global = TRUE i can replicate the whole row from dbMaster.aTable to dbSlave.aTable
If Global = FALSE i cant replicate any row from dbMaster.aTable to dbSlave.aTable

This I do it using a filter on global column at the sbMaster Publisher

My problem is at dbSlave side

If Global = TRUE i can replicate back to dbMaster.aTable only price andcantity values ... the id,name and global columns I cant modify
If Global = FALSE i can replicate back to dbMaster.aTable whole rowcreated in dbSlave.aTable and Global will be FALSE too indbMaster.aTable

hope someone understands what i'm trying to say here and give me an advice

thank you
