I have taken over responsibility for an access database not designed by me that I need to clean up. I have a table that I need to find out how it is calculating data. I can't find that it is based on a query and when I click on relationships, it says it has no dependencies. However, this information is not manually input. It is a total of amounts for a certain UPI code (package) that include certain service codes. (The UPI codes and what service codes are linked to them are part of another table). The amounts come from another table that includes service codes. When I run a pivot table on the data I cannot match the number in this table.....so I would like to find out what service codes this calculation is using. Any ideas?
