ASCP Plan failing at Loader Worker With Direct Load with Unique Constraint MSC_SUPPLIES error

ASCP is being used with integration to Oracle Production Scheduling. After publishing a schedule from Production Scheduling, The ASCP plan run is failing at the Memory Based Planner, Loader Worker With Direct Load Option stage. We have just gone live with Production Scheduling and ran the full integrated cycle for 5 days with no issues. On the sixth day, the ASCP errors every time after publishing from Oracle Production scheduling. The only way I can get the plan to complete is by deleting records from MSC_SUPPLIES table, which compromises the planning data.

Record #######: Rejected - Error on table MSC.MSC_SUPPLIES, ORA-00001: unique constraint (MSC.MSC_SUPPLIES_U1) violated

The issue can be reproduced at will with the following steps:
1. Launch Production Scheduling: Production Scheduler > Production Scheduler> Launch
2. Open the PS Workbench and perform scheduling Production Scheduler > Production Scheduler > Workbench
3. Approve and publish the PS schedule. SCP Integration concurrent request launches, as a result of publishing, and completes successfully.
4. Launch ASCP plan.
5. ASCP Plan fails
