Concurrent Capacity and scheduling error

Wondering if anyone has had any luck with Concurrent Capacity and scheduling? Our machines have plates, (resources) that hold various size molds on each resource. The molds are set up as resources with various size capacities. The plate has a CC of 8 and the molds vary from 1-8. When a sales order is entered and MRP runs. The jobs are scheduled until the 8 different plates on the machine are full for 2 days. We are backward scheduling and it fail if it has to look further than 2 days.
Moving to E10 and expected this to work better.
