Yes, it can be done.
Assuming you have an external database table called Orders with a field called ob_Customers
1st, change the name to ob_Customers_RID (the RID is the foreign key)
2nd, add 2 columns, the REN and RMA. The RMA can remain null, and the REN has to have the text "Customers"
Now, have aware CREATE empty an empty database, shut down aware, restore your good MYSQL table (or whole database) and now Aware will be happy
OK, only sort of happy. Each Aware table has 3 columns, ID (which you probably have), BASVERSION (which can always be set to 1, and BASTIMESTAMP (put in todays date.)
Now Aware is pretty darn happy!
