WIP becomes Inventory, when Component is made

We have a large prod. BOM, with several levels of components (NA 3.10). The components are being backflushed and has routing link codes attached to them. When an output journal line is made for a lower level component (without checkmark in finished) and posted, the WIP account is credited with the components value and the inventory (Raw material) is debited. We want to keep all cost in WIP until the parent item is produced (Output journal line with checkmark in finished), so all should go to WIP until the production order is finished. what settings do we need to make? is it possible?

So why are you using routing link codes?

Hi, You should not use subcomponents in the BOM for Finished Good. Use BOM option instead Item Option in the BOM lines for the finished good.
