HQId=0 @ Stores after TablesSync for Custom Tables

Hi I use the table sync to send data down to stores from my custom tables,i noticed that the HQId field @ the Store dosent reflect the respective one at HQ,instead it gets the value 0. Thats creates double work and chances for collation issues for the Custom application. Can anyone help on this please ASAP as itz pretty urgent. Thanks in advance Regards Zak
