I recently set up a new item with a router and work centers.  The cost is populated on the work center card and I have left them as 0.00 on the router card (same as every other item we've ever set up).  For some reason, when I create a production order, (the flushing method is backward), post the production order, close it, and then refresh the cost no costs are posted against the output item I just made.  There are also no costs in the capacity ledger, values ledger etc.....

We have verified the item is set up like it's counterparts and haven't seen any differences.  Any help/thoughts would be appreciated.
