Sql Server 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 and cantity values ... the id,name and global columns I cant modify
If Global = FALSE i can replicate back to dbMaster.aTable whole row created in dbSlave.aTable and Global will be FALSE too in dbMaster.aTable

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

thank you
