Wanted to post a solution I found in case it can help others.
Working in ArcGIS Pro and model builder to run Location Allocation Scenarios on multiple markets. I have a listing of seedpoints that are both Required and Candidates. When I loaded them into the location allocation tool I pointed the Facility Type to my fields that indicated "Required" or "Candidate". After running the tool, I noticed none of my "Required" sites were recognized as required. Finally found documentation that seems to be from ArcGIS online rest points, that when using a field to determine Facility Types, "Required" needs to be coded as a 1 and "Candidate" needs to be coded as 0. I did not see much documentation on this so I figured I would post to this message board. Hope this is helpful.
Documentation that helped me find the solution: https://apps.firstmap.delaware.gov/apps/sdk/rest/index.html#//02ss000001vw000000
I can see how this would be confusing. The FacilityType field uses an integer domain to represent the various types of facilities. The correct documentation link for ArcGIS Pro is here: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/location-allocation-analysis-layer.h...
