CTP - Planning direction "Forward"

Hello experts.

Anyone knows how to make the CTP using the planning direction to Forward?

The standard are "backward" or "backward+reverse".

For example:

Week 38 - Free capacity

Week 39 - 100% occupied.

Week 40 - Free capacity

Week 41 - Free capacity

if the sales order is created on Week 40, the planned order will be created at week 38.

Our customers don't want stay with stock during 2 week (even 1 day allowed).

They prefer delaying the order instead maintain stock.

I'm trying fix the resources during the ATP, works (I'm testing now) but if there is a better solution, i would know

Best regards
