Ruled based ATP and Checking horizon

Hi Experts

I have one issues

when I activate the RULE based ATP in the checking instruction and it works well, but the system can not use the checking horizon function, this will cause if there is no enough stock in the triggering plant and substitution plant, the system can not confirm all requirement.

I want the system works like this
1. first check  stock in the triggering plant and substitution plant , if the substitution plant has a stock the system will generate a STO order

2. if there is not enough stock in triggering plant and substitution plant, the system will confirm the remaining requirement in the triggering plant using check horizon.

how to do  that?

does anyone have encounter this issue?

by the way, I have tried if I activate the RBA in the checking instruction and checking horizon in the check control, the RBA will not work, the system will only confirm the trigger plant stock , even if the substitution plant have enough stock , the system will ignore them.

if I only activate the RBA, the check horizon can not not be used.

I want to use both.

thank you in advance!
