Transfer material from Valuated project non valuated project

Hi Experts,

While i am trying to transfer material from Valuated project stock to Non valuated project with T.Code MB1B movement type 415 'Q', I am getting following error.

WBS element has different inventory valuation

Message no. CN769

Diagnosis

The project definition for WBS element only allows the following stock control:

No project stock

No project stock with defined valuation M

' ' = non-valuated project stock

'M' = valuated project stock

System Response

Account assignment not possible.

Procedure

Change the settings for the project stock in the project definition (Control tab) or use a suitable WBS element.

Kindly suggest me how to trafer material from Non valued project stock to valuated project stock.
