the following idea would prevent errors in imported parts, Purchased Parts standard Parts etc.
the Idea is as following.
- the admin would create a set of criteria for an Item.
- if this criteria is applicable. Users are not allowed to checkout this item. only admins.
- the criteria would be for example but not exclusive.
- a Prefix or a group of Prefix in the Item Number.
- a combination of Item type and item status.
this idea would reduce errors and create more secure System for standard, Purchased Parts or Imported Parts.
