Hi Steve,
The reason why you see materials which are blocked for purchasing is as
follows.
A material can be purchased, sold and it can also be present in the
inventory. When you block it for purchasing you can always sell it and
also it can be present in your inventory. Also sales can be blocked but
you cannot delete it from the inventory. Hence you see this material
although Sales and Purchasing is blocked.
1. How to make a Material Obsolete?
Material is a Master Data, so once it is created then its not possible
to delete but you can block the material partically. You are allowed to
block only the Sales and Purchasing of a material and status of
Logistics, Planning, Availability Confirmation, and Valuation are not
allowed to block. The reason for this behavior is, if the material is
used for Logistics, Planning, Availability Confirmation, and Valuation,
blocking the status will end up in inconsistencies in the Business
transaction Documents whichever uses the Material.
2. What is the status of the Material after blocking the Sales and
Purchasing "Blocked"?
When you set the status to "Blocked" for Sales and Purchasing, then
those materials cannot be consumed by any Sales (CRM) and Purchasing
(SRM) business transactions. You may find the Material in the value help
but when you assign, system will throw error message.
