Reorder quantities - Sage 300 2014 PU3

My client wants the system to reorder to the Max value under the following conditions:

In I/C  Items & Price Lists > Reorder Quantities

Min Qty: 0

Max Qty: 5

Reorder Qty: 0

I have tested this scenario out and ordering to the max does not happen and it works (not surprisingly) when there are values for Min and Reorder and the system reorders for the difference between the Max value here and Qty on Hand + Qty on PO - Qty on SO in Location details.

Does anyone have any thoughts on reordering to the Max value under conditions mentioned in the first paragraph?

Thank you
