The PR AD AH column (Planned Receipts Based on Availability Date (Aggregation Horizon)) displays the total quantity of all planned replenishment orders whose availability date lies in the aggregation horizon. The quantity is displayed as a link. The link opens a dialog box but keeps the RR Overview screen in the background. The dialog box displays the planned replenishment orders that contribute to the quantity value. In the dialog box, you can create, change, or delete planned receipts for the product under consideration or for another product. When you save the changed data in the dialog box and close it, you return to the RR Overview screen that displays the updated data.
