The S-parts list shows all incorporated stocked parts of the selected part for which you have created a pre-calculation.
Here you can see quantity, material cost excluding SO, SO mark-up, manufacturing cost, subcontracting cost excluding SC and SC mark-up. In the last column you will see the lot size in red if the requirement exceeds the lot size. The lot size, on which the calculation is based, is shown in a separate column. This applies for both the Do not explode and Recalculate alternatives for S-parts. If you have selected Recalculate under the Create tab, you will see the EOQ and a warning if the EOQ or calculation is missing for the parts. At the bottom of the list you will see a total sum of the incorporated columns.
If an explosion of the incorporated S-part is made, the part will be shown under the M-parts tab instead. This makes it easier to see from where the totals originate under the Summary tab.
