I have created one material abc111
If i want to change this material to def111,is it possible?
Problem is ,number of materials already created for which i want to change prefex as i asked above
OR I need to create these all materials once again
can I block/flag for deletion the material?
Even if stock exists and some open orders are there with this material
what is the difference between block and flag for deletion and in future can i restore from block/flag for deletion?
Please guide me
As per your requirement.
You can change the material abc111 to def111, if any transaction is not done against material abc111 also it have no single quantity of stock.Just change material master detail with MM02.
But if material have any transaction or stock.
Then you have to create new material for def111.
If you want to delete of block material, you can do it with MM05 - Blocked and MM06 - Deletion flag for material.
Difference between block and delete of material.
If you have material which is useful for u, but due to some problem purchase of material is restrict for some duriation at that time you can block material.
And if you have material which is not useful for u, so you can delete it with MM06.
You can change both status of material with same t-code MM05 and MM06.
