Non valuated material

Hi Gurus,

I want to create a non valuated material which should have the stock updated and should not update the value.

dummy material

My scenario is like I have a material (soft copy) which i will give it to vendor to print the books.In this case the Soft copy will become a sub contracting material and same material will be taken back insted of components.

In this case the soft copy should serve as information purpose and should not affect any FI accounts.the purpose of this is to track the soft copy whether the vendor has return or not.

I created the soft copy as Non valuated material and books as a trading material.

I raised a PO with this two material,one as sub contracting and another as standard material, but in the system is asking to enter the cost center and GL account for soft copy.

So here how to avoid this financial interaction, since this material is only for information purpose.

Kindly guide me

Regards,

Sri......
