Hi Ryan,
You can try the below thing.
Instead of using QUOMO feature to specify quota groups, you can use a custom PCR of MODT to specify quota groups using operation MODIF.
In this custom PCR, read the value of time type getting generated from function P2012 and if it is greater than 0, it means that base entitlement is coming from IT2012. If it is greater than 0, then specify quota group 02 and if it is equal to 0, then specify 01.
Rest of the things will remain the same. You will have to remove the configuration in feature QUOMO so that it doesn't override the value determined in custom PCR.
I hope this information is helpful for you and will resolve your issue.
Thanks and regards,
Vivek Barnwal
