Hi Sachin,

In Mendix, when multiple access rules are defined on the same entity, they are evaluated using an OR logic. This means that if a user satisfies the conditions of any one rule, they will be granted access as defined in that rule. To ensure that these rules work as intended, it is important to write each rule with precise XPath constraints and role restrictions. This avoids unintentionally broadening access due to overlapping permissions. Each access rule should be crafted carefully, especially when different module roles are involved, to prevent users from gaining excessive privileges. It’s also important to test access with different combinations of user roles to confirm that each role only sees or modifies what it is allowed to. Additionally, make sure that inherited module roles are taken into account, as they can also grant access through parent modules. For complex cases, combining entity access rules with role-based visibility on pages or microflows can offer more granular control. Overall, access rules should be reviewed regularly and tested in context to ensure they enforce the correct level of security.

Hope it helps!
