Customers in Dynamics AX Retail POS

Hello,

I thought that if I run the N-1010 Job to copy the Customers in a Shop that all Customers would be replicated in the Shop. In other words I thought that if I run the N-1010 job all entries in the CustTable from HQ will be mapped (1 to 1) in the CustTable in the POSDB.

Apparently this is not the case since I am missing about 0.1% of the data.

Do I have to put the Customers in some sort of Address Book or something?

Thank you!
