Resource Variance Calculation

We have just gone live on a very patched implemetation where base data quality is poor.

 We are on a standard costing system.  When I review some samples of wip transaction distributions, I am seeing not only the standard cost entries but also seeing the system multiple the current times on the routers by the quantities on the jobs and post a variance for the difference between standard and the router.

I have never seen a standard cost system post entries like this to the GL and although the information about the differences can be informative - I don't want it booked to the GL.
