Salesforce applies platform limits to the number of sharing rules configured for an object. The standard allocation is 300 total sharing rules per object, including owner-based and criteria-based rules. This limitation matters when designing a franchise architecture because creating separate sharing rules for every franchise, region, or user population can result in an unnecessarily complex sharing model and eventually approach platform limits.

Architects should prefer scalable mechanisms such as roles, public groups, role-and-subordinate relationships, sharing sets or appropriate Experience Cloud sharing constructs, and criteria-driven sharing where those mechanisms meet the security requirements.

The default total sharing-rule limit can in some circumstances be increased through Salesforce Support, but the standard architectural limit tested here is 300 rules per object.

A user occupies one role in Salesforce ' s role hierarchy, not multiple simultaneous roles. Browser selection is unrelated to the fundamental role-and-sharing architecture. Public groups are supported as reusable sharing targets, but the stated 1,024 limit is not the relevant restriction identified in this scenario.

Therefore, the architect must account for the per-object sharing-rule allocation when designing a large franchise access model and should avoid a design that depends on a separate rule for every franchise unless absolutely necessary.
