There are two relevant tables for this report, 'Parts' and 'Part Requests'. The Parts table is just a list of all available parts with their available stock, and the Part Requests fields include 'Related Part', 'Quantity' and 'Project Number'.
I have a request for a report where users can enter the project numbers for the projects they are focused on, and they want to see the quantity on hand from the parts table compared to the sum of the quantity requested in the Part Requests.
My problem is I cannot figure out a way to give them a dynamic filter for which project numbers to use.
I was hoping if I just did a table report then they could just use the column filters, but they aren't giving the drop down with the option to select multiple project numbers but instead are just giving the single the option to enter a single text string.
