P4021 (ATP) - Business days for ATP Calculation instead of Calendar Days for Procured Parts

 Hi,

Environment : JDE World Soft A7.3 Cume 11. We have defined a Manufactured item as Stocking type - "M" in Manufacturing Branch plant. This part is sold from a selling/distribution  branch plant where it's defined as purchased item. (Part is made available in selling BP by ST /OT orders between manufacturing and selling branch plants couple of times during a day,so the lead time for this part is same in both the branches). When a sales order is created and this item goes on backorder ,exit to P4021 pulls up the available promise date as today's date plus lead time
