I have sheet that contains master data for customers. The master data customer sheet has a set number of support hours available for each customer. I have another sheet that is collecting support hour information for the customers. A summary field has been created for each customer that sums the support hours for that customer.
Is there a way to reference the summary field containing support hours for the customer in a formula in the master data sheet? I would like to build a report or dashboard that would show the available support hours for each customer (Total support hours available - sum of customer support hours used = total available customer support hours).
