To restrict record access based on a custom picklist value, add a single picklist to your restriction or scoping rule. Single picklists are supported in record criteria, but multi-select picklists aren’t.
Where: Restriction rules are available in Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions. Scoping rules are available in Lightning Experience to customers using Unlimited or Performance Edition with Signature Support or Program Architect or Technical Account Manager professional services.
How: To use a picklist in your rule’s record criteria, navigate to Object Manager in Setup and select an object. Click Restriction Rules or Scoping Rules. Name and describe the rule, and then activate it. Select a picklist as the type field in record criteria, and choose a picklist value to determine the records that the rule applies to.
