Flushing Method Problem (NAV 4, SP3)


I am trying to change Flushing Method from “Manual” to “Backward”. I have changed it on the Item Card, but when I create a Production Order from a Sales Order and then try to post it, nothing get’s consumed automatically. If I open up the Production Journal and change the Flushing Method Filter to “Backward”, nothing gets listed, but I can see my Item if I change the filter to “Manual”.

What am I missing? I thought that if I had chosen Backward Flushing I then wouldn’t have to use the Production Journal since consumption and output should be posted automatically?

NAV verison: UK 4, SP3.

Any help is greatly appreciated!
