variance relieved $$ in non-standard WIP job is getting posted to Deferred COGS during sales order i

 We are running non-standard repairs using Oracle WIP.   This is a FIFO costing environment.

All different items have non-standard WIP job completed. There are costs incurred, cost relieved, and variance relieved in WIP value summary.

Cost incurred are sum of previous level incurred and this level cost incurred.  Cost relieved is equal to this level cost incurred and variance  (material, resource, overhead) for the non-standard job is previous level cost

After repair WIP jobs are completed and closed, units are shipped back to customer. 

For some items, variance relieved $$ amounts for material, resource, overhead are getting posted to Deferred COGS at the time of sales order issue. We expect that THIS LEVEL COSTS RELIEVED should be getting posted to Deferred COGS
