Example: Rounding (Using Unit Conversions in
the Sales Order) 
The following example is illustrates how the results of rounding quantities are displayed in the sales order, if the unit conversion used in the sales order does not correspond to the package units used in a location.
This example is based on the example Example: Rounding (With RBA – Not Enough Stock in Location 1000). The package units in Location 2000 do not correspond to the unit conversion used in the sales order.
The following criteria applies:
Location |
Package Unit |
Rounding Rule |
Stock Available |
1000 |
6 pc / 12 pc / 18 pc |
Up |
10 pc |
2000 |
5 pc / 10 pc / 15 pc |
Up |
20 pc |
The unit conversion used in the sales order is 1 pack = 6 pc.
In this example, not enough stock is available in location 1000.
...
1. The requested quantity for the sales order item is 2 packs (12 pc).
2. Location determination takes place; location 1000 is found.
A subitem is created for location 1000.
3. The 2 packs are converted to 12 pc. For location 1000, the 12 pc are rounded - 12 pc are ok (that is, rounding up is not necessary).
4. Only 10 pc are available. Therefore, the ATP check can confirm only 10 pc.
5. The 10 pc are rounded down to the next package unit of 6 pc.
6. The requested quantity is higher than the rounded (confirmed) quantity. Therefore, there is an outstanding requirement of 6 pc.
7. Location determination takes place again; location 2000 is found.
A subitem is created for location 2000.
8. For location 2000, the remaining requirement of 6 pc are rounded up to 10 pc. Therefore, the requested quantity is 10 pc (2 packs).
The requested quantities for both subitems (2 packs and 1 pack) are accumulated in the rounded requested quantity schedule line of the main item.
9. The ATP check can confirm all 10 pc.
10. The 10 pc are converted to 1.7 pack. For the sales order, this does not look “rounded”, but for SAP APO, this is rounded (2 packs of 5 pc each).
