Situation :
a form modifying a parent table with a ono_to_one relation to a child table (eg INVOICE_HEADER related to CUSTOMER using CUST_ID)


How can I force the CUSTOMER table to change to the correct record when the CUST_ID is changed (interactively or programmatically) on the form. As soon as I change to another record in the parenttable the customertable moves with it, that is not the problem ...
