Sort Production Orders Report Problem

When printing multiple Production Orders (using Print Production Orders process), I want to be able to sort all the orders by the Workcenter in which they start. The reason is so production orders can be distributed to each work center without manually sorting. The default is to sort by Production Order ID.  I am playing with the sort properties but not having much luck:

I have tried to change the property from oAMProdItem.ProdOrdID] to AMProdOper.WcID:

I’m not having any luck the sort order remains the same sorting by ProdOrderID.

Any help is much appreciated.

thank you
