On a SharePoint Online I have this mapping of Managed Properties in the Search Schema:
Site Collection A : RefinableString10 -> ows_BuildingNumber
Site Collection B : RefinableString10 -> ows_EquipmentNumber
Site Collection C : RefinableString10 -> ows_BuildingNumber
In order to consolidate across the Site Collections, I plan to map RefinableString10 to ows_BuildingNumber on the Tenant level, and remove the mapping on the individual Site Collections.
Had I used a new RefinableString, like RefinableString20, the mapping on the Tenant level percolates to the Site Collections, however it seems like once a managed property has been used on the Site Collection level it will no longer receive the mapping from the Tenant level? I have tried running Mikael Svensons "Force full crawl on SPO" script, but it does not seems to resolve the issue.
