APS Partitions for Production Scheduler

Hello,

When creating Plans (Names) in Production Scheduler that are to be exported to Production Scheduling, is it necessary to run the request "Create APS Partitions" with plan_partition_count=1; instance_partition_count=0; everytime we create a new Plan name?

If we don't run this request, and try to create a new Plan (name) we get an error stating that there are no Free Partitions available.

We are on a Centralized instance, 12.2.5.

Profile option: MSC: Share Plan Partitions is set to NO.

Error without the request "Create APS Partitions" with plan_partition_count=1; instance_partition_count=0
