STO from GR Blocked to Gr Blocked

Hi,

We have one scenario in which HQ procures a material and tranfer it to different sites.Client want that material is not be valuated till its accepted by the sites.

So I want to receive material at HQ in Gr blocked stock .

But my question is

Can we create a stock transport order from one plant (Gr Blocked) to another Plant (Gr blocked).

Please Suggest the possible solution.

Regards,

Vijay
