I am building a massive app with customer portal.

The users that will connects will be parts of companies.

So I need every users of the same company to view/edit only the records of the company. Sadly, it is not possible with the customer portal to do this type of profile/permissions.

I was thinking about dataset.

Is it possible to build different folder(dataset) in the backend? Each company would be a dataset.

After that, I would apply permission of the dataset based on a list of users per company.

I have already spoken with tech support and tried bidirectional lookups with tables but that didn't worked.

Thanks!
