I am trying to understand how the information on the Shortage List is calculated. The example that I have is I have a qty. on hand of 25 pcs. I have a Qty. on Component Lines of 40. I have 0 on a Purchase Order. Logic would tell me that I need to order 15 to fulfill my requirements. However, when I pull the shortage list it tells me that I have a Needed Quantity of 44. Here is what it looks like to me.
25 quantity on hand, I have the following requirements that are not on the shortage report 6 pc each for Production Order 15, 16, 17, 18 and I have 1 pc for Production Order 19, which would consume all of my 25 on hand. (6x4+1 = 25) The first time the part shows up on the report is for Production Order 19, for 3 pc and for some reason the Scheduled Needed column has 29 pcs. The component shows up six times on the report and bottom line is I need to order 44 pcs, which to me is not correct. I feel that there is a parameter set incorrectly somewhere but I am not familiar with the system enough to know what it might be. If I could understand where this number is coming from I think that I could understand the report.
Is there a report that will give you the shortages by part combined together instead of by Production Order ? All I need is a report that would take each part that has a quantity in the Qty. on component Lines field, subtract that from the Qty. on hand field and subtract the Qty. on Purch. Order and give me a quantity that I need to order ? Is there a canned report for this or can I create one ?
