Thank you for ur valuable points.
Firstly Material is moving avarage price.
Secondly Vendor need to give full payment.
Thirdly I am adjusting my inventory value on actaul material after quality checking.
4)Vendor is producing invoice at the time of goods supply
5)Because vendor invoice coming at the month end time so my material is consuming.So i can not adjsut invoice receipt.
So i have only one option is once GRN is done my new rate should hit to inventory value.
