The S-parts tab is used to show the details of the material cost for all incorporated purchased parts of the selected part for which you have created a pre-calculation.
Here you can see the order point and requested point in work days in relation to the selected finish period, quantity, price each, material cost without the SO, SO mark-up, supplier code and purchase price. At the bottom of the list you will see a total sum of the incorporated columns. The Start and Finish columns will affect the throughput time, including the material procurement that is shown under the Summary tab. The highest value for a part with lot sizing rule L (Lot-for-lot) appears in the Summary as the Throughput time (including material procurement).
If you have activated the setting Use SO/SC mark-up exceptions in the system, which you will find under the heading Calculations under the Manufacturing tab in the Settings procedure, the list will also show whether this part contains such exceptions.
If the setting Use staggered sales/purchase prices on parts? is configured, under the heading Price management that you will find under the System tab in the Settings procedure, the list will also show staggered prices in the Each column and quantity in the Staggered quantity column. This will apply if the part has got a staggered price for a smaller quantity on the current supplier link than the part's requirement in the pre-calculation. Otherwise, the list will show the part's regular purchase price and staggered quantity = 0.
