Can anyone explain the difference of the parameter Circularity check strategy under Inventory and warehouse management parameters > Bill of materials:

What is the difference between Optimize for high complexity and Optimize for low complexity?

Thank you!

Hello Markus,

I found the following explanation:

The Optimize for Low complexity will request data from disk as it is needed for the circularity check. For single level/simple BOM structures performance will be better by selecting this option for the Circularity check strategy.

When Optimize for High complexity is selected as the Circularity check strategy, the BOM structure and all of its’ dependencies are cached before the circularity check is processed. When processing a BOM with many lines it may take a moment for the processing to start since it is loading the information into cache. However, the Optimize for High complexity can significantly improve overall performance of the circularity check. This is especially true if you are running a task that will be performing a circularity check on multiple BOM’s or if you are doing a consistency check on the Bills of materials.

There are new-ish scenarios where BOM Circularity is supported. To enable these scenarios, this parameter must be set to High Complexity. (If you have access to LCS Issue Search KB3089402 is one).

Essentially, always set this parameter to High Complexity.
