I am trying to track actual labor invoiced vs. projected labor costs by project. I have 4 tables that all relate in some way: Projects Table- contains the name of the project etc., Rate Card Table-contains a line item by line item rate for each task, Invoices Table-pulls the project name from Project, the Item # and Description from Rate Card and calculates total invoiced based on quantity input, the Projected Labor Table-contains projected costs per line item in the rate card per project (for example the line item A-1 (dig hole) appears once per each project, but each project only has one A-1). The invoices are input on a daily basis. I'm trying to create a "draw-down" report that shows projected labor costs vs actual invoiced labor costs on a per line item and per project basis. What I really need is to somehow summarize each invoiced line item on a per project basis in the Invoices Table and subtract that from the Projected Labor costs in the Projected Labor table on a per line item per project basis. I hope I have summarized this correctly I've been trying to figure it out all day and am now thoroughly confused!
