Cross site lookup
We are using SharePoint online we would like to access top-level site list data to subs site. for example, we created the customer list in the top-level site. we need to use this data to all subs...
Jeyganeshthird-party solutions exist for these kind of scenario's. I know they exist but haven't used them myself.
However, you could consider to make use of Managed Metadata Term Sets instead of SharePoint lists. You could for example create a Customers Term Set to store the most important data to be able to identify a customer and reference this using Managed Metadata columns from all your subites. If you need to store more data around these same customers you might still also have your central "Customers" list optionally also pointing to this same Term Set and create a custom developed synchronization mechanism to prevent maintenance of your customer lists in more than one place.
Hope this helps!
