It would be beneficial to be able to roll up standard from a purchased item to the items will bills of material where the purchased item is used. Currently the calculate standard costs is only top down.
Companies have requested in the past to be able to adjust the standard in the full where used of the purchased item(s) (sub assemblies and parents) possibly even for any purchased items that were changed in a give time period vs having to roll up all production order items.

Example:
Purchased item A has a standard of $1.00, the standard cost on the item is changed to $2.00 based on the cost to purchase the item changing.
The company then would like to roll up all items with Bills of material where the purchased item is used (including sub assemblies and parents) based on the new standard cost of the purchased item.
