Cost Relieved for Non-Standard work order

Hi All,

I would like to know how 'Cost Relieved' calculate in 'WIP Value summary' for Non-Standard work order when we have

1. Routing reference

2. Non-routing reference (manually added operations) and

3. Routing reference linked but deleted few operations sequences in that work order.

Costing Method: Standard Costing

We created a non-std work order using scenario: 3 and the cost relieved using assembly cost. We thought the cost would relieve based on the operations used in the work order.

Now, the cost relieved is more than cost incurred. can someone help us resolve this? Thanks,
