Third party order processing in Thailand

Hi,

does anyone know that for third party order processing in Thailand, where goods are shipped directly from the vendor to the customer, is it a legal requirement for Thailand to keep track of the in and out movement of the goods in SAP although the goods did not actually come in to the company before going to customer?

If that's the case, how can we handle this in the SAP system? Do we need to do goods receipt and then goods issue out from the inventory to record all the movement for the direct shipment?

please can anyone shed any lights on the above.

Thank you.
