Groovy Code to Determine Valid Intersections

Summary:

We have a valid intersection to define the business unit for each department (every department belongs to only one BU). To make business rules more efficient, we want to determine those relationships, so data grids can focus on the BU for the specific department being calculated.

Content (required):

Currently, we use a separate grid to pull departments for all BUs and use the method isValidIntersection() to create a map. But this grid must be run department by department (to prevent cell limit error) and takes considerable time for upper-level department nodes. Ideally, we would be able to access the VI directly to make the map. Has anyone come up with a clever solution for this?
