Hi Josh,
i have attached a screen shot of our Projected Sales Order Shortage Data, highlighting one row as an example, so when the multi level pegging process runs, it links every demand (in this case Sales Order) to the supply (in our case the Stock satisfied by Jobs as our strategy is Make to Stock) starting with the sooner Job Due Date, so in my example order no. 8192 line 1 rel 16 will be late 17 days ( the difference between the Need by Date 1/10/2018 and the Pegged Job 038286 Due Date 18/10/2018) this is the max days overdue if planned do not change scheduling to avoid this i can not see any different in value between max. days overdue and days overdue in our data they both the same value, now the shortage qty is 84 which the different between the Rel. Required qty 160-off and what the linked jobs to supply in this case 4 left over from Job No.038220 and the whole job No 038286 qty 72-off, So (160-4-72=84), you can see on the lower dashboard all other releases and their links as well.
i hope this helps.
