Can you link tables based upon a formula result? I have 2 tables: FINA_ALL and AR. I need to link the two tables based upon Invoice #. AR contains the field Invoice#. FINA_ALL has a field TRANS_TEXT which is a combination of the customer code and invoice#. I can extract the invoice# by using right(TRANS_TEXT,6). How can I link the result of right(TRANS_TEXT,6) to the AR Invoice# to retrieve additional details from the AR table?
