RF31210 Variances



I have lean completions occurring using PF31011, and overnight RF31200 and RF31210 run to book entries and variances. A large variance is occurring for an item, whose cost appears to be pretty simplistic. The frozen and simulated costs are equal on this part, and no BOM or routing changes have occurred on the part.

When I look at the completions on PF31014, it shows me the variance is due to my planned and actual A1 amount being $0, but my standard, current, and completed amounts being equal to the variance generated...

Does anyone know what would cause this? I'm confused because I feel like all A1 costs for standard, current, planned, actual, and completed should be the same.
