Is Non-Standard Discrete Job considered firm supply automatically by ASCP?

can anyone point to ny documents or Notes referring to what is the expected behavior in ASCP for Non-Standard jobs? In 11.5.10, I see the behavior, that planning engine considers a Non-Standard Job as a firm supply and pegs, schedules accordingly.

whereeas in 12.1.3, post upgrade, I see that the Non-standard Job is being considered as a Non-Firm supply.

Found a Metalink Note for 11.5.10 version, which says that Non-Standard Discrete Job will be considered as a firm supply. Why was the behavior changed in 12.1.3 or are there any setups which can configure the same in 12.1.3

Any help is appreciated.

Thanks
