Logistic required CS to list “request invoice” mail because there is more lead time to generate invoice by received 2 things not only received FG but inventory has to receive supplier inv also. Below green mail has no Drover.
In the past, in order to support sales, inventory received FG to system as “dummy” 1 time and once supplier inv came, sometimes they key received again and generated double received quantity cause inventory error.
So they agreed with you already to use request inv system to be able to follow and collect supplier inv with less effect to deliver plan. So it is hard to request shipment and expect to ship immediately.
Production is reviewing SO/SX that affected with few additional external factors. Does not mean all shipment will be extend but production will reduce lead time by increase safety stock.
PS. Only received FG without inv is not only affected this, it impacts more few things that make confusion to production process. Soon I will show everyone for overview.
