In relation to 'purchase of material' we debit the raw material inventory account because material is increasing and is an asset account; and we credit Bank if the materials have been paid for OR 'accounts payable', if the material has not yet been paid for.
In relation to 'requisition of material for production' we debit the raw material inventory account because material is decreasing and is an asset account; and we credit 'work in process' to assign the cost of materials to the ongoing jobs respectively.
