We're currently working Navision Classic 2009, Manufacturing environment.
Struggling at the moment to keep on top of items that are more suited to being on KANBAN as opposed to automatically adjusted inventory stock. We need to have these items on the Production BoMs such that the respective costs are pulled together into the complete machine cost (for quoting purposes etc.) however don't then want the respective Production Order generated from this Production BoM to incorporate the costs for these items. Essentially we don't want to book these items against the Production Orders as the quantities aren't necessarily accurate, and are mostly very low value but relatively high usage parts (fixings etc.).
What I want to do is enable these items to have the inventory manually adjusted every time the box is emptied (i.e. the inventory would be 100 when there's a box on the shelf, 0 when no box and nothing in between). This cost would be booked to a consumable cost centre which we already have set up.
Currently these items are on backwards flushing, so whenever a Pick is created the system automatically consumes the number of fixings on the BoM to said build and reduces the inventory by that amount. Problem is that these items are line side so fitters just grab a handful whenever they need them, meaning the inventory is immediately incorrect on Nav and as such we have no end of stocking issues (either way to many or way too little). Essentially we want to make this a manual process, but still enable the costs of these items to be pulled through onto the standard cost of the Production BoM but not then considered on the Production Order, otherwise we'll end up either a cost variance (if the items are ignored on the Pick for example) or the inventory is always going to be incorrect.
Does this make any sense and, if so, is there a function on the item card that can be selected which will allow the above?
