Oracle Process Manufacturing Process Planning - Version 12.0.0 and later Information in this document applies to any platform.
To describe what is a circular reference and how ASCP manages their existence in an OPM integrated environment
Why is it Important?
ASCP does not support Circular References. One of the existing enhancement's is <bug 3380269>: ASCP NEEDS TO BE ABLE TO PLAN CIRCULAR REFERENCES. It should not be anticipated that this functionality will be made available in the near term.
ASCP and OPM/ASCP addresses this issue by stripping the circular reference before they get to the Memory Based Planner. If this was not the case then, as the circular reference can constitute both a supply and a demand to the planning engine, the planning engine can enter an infinite loop. In turn this will lead to the plan failing and so no results will be available to the users. To avoid such a circumstance the circular reference is stripped and thereby allowing planning to complete.
For the items that are subject to circular references it should be noted that the stripping (removal) referenced above will mean that demand is not passed the whole way down the supply chain in these cases.
