Interesting problem with the Product Cost Structure report but I'm not sure if it's a bug or a configuration problem.

I setup a Work Center with everything set to 1 (Efficiency, capacity, time for 1 cycle) Cost per hour I set at 18.32 and Cost per cycle as 4.40

I setup a Routing which uses this Work Center for a number of work steps, Number of Cycles and Number of Hours are identical (because 1 cycle takes 1 hour)

I attach the Routing to a Bill of Materials, go into the Product record and ask it to print a Product Cost Structure Report.

Looking at the report, the cycle costs are correct but for some reason the Hourly Cost is doubled.

When I look at the Work Orders tab in the Manufacturing Order, the number of hours is doubled from the figure that appears in my Routing, can't see any reason why this should happen.

I'm using MRP and MRP Operations modules

Any ideas if it could be my configuration ?
