# 16.7 Advanced Sharing Access

This allows you to extend data access permissions for a user on a specific module, based on rules defined according to the same logic as filters. Let's look at an example: the Milan Agent user must be able to access the Account registries (all of them, even those assigned to others) for the province of Milan.

**STEP 1:** Add a rule in the Accounts module, then configure the rule. In our example, on Accounts&Contacts the rule will be a Province equal to Milan.
