Process Doubt

Hi Experts,

We have 2 Plant A and plant B.

Plant A is ordering material to vendor.

Vendor is delivering to Plant B.

Plant A is paying to vendor.

Now how to make the stock in Plant B.

We are doing Costing in Plant B also.

Please tell how to process this scenario. (If it is Plant A to customer , we handle through Third Party Process.)

thx in adv......
