I have an "order details" table that needs to populate a field called "Voucher" with data from another table called "codes". The "codes" table also has a true/false field called "allocated" because once allocated the code cannot be re-used.
I am trying to work out how to automatically allocate the next unallocated code in the "codes" table to each record in the "order details" table when that order details record has a DiscountID of "92".
Order Details Table Fields and conditions/criteria:
ID - primary key
DiscountID - only when the DiscountID = 92
Voucher - only populated when Discount ID = 92
Codes table Fields and conditions/criteria:
ID - primary key
code = text field with a code like "einstein01", "einstein02"
Allocated = False
Is there a way to put the next available code into the order details record then mark that code as allocated in the codes table. Then, move on to the next order details record that has a discountID = 92, input the next unallocated code and mark that code etc. etc.
Ideally, I would like to do this to happen via an event when the Order forms button "Close" is clicked. Any help would really be appreciated.
