Sharing is complex, but necessarily so. It gives you incredibly fine-grained control over data access through it’s flexibility but requires quite a deep understanding to do it properly.
There are great articles out there that describe sharing in detail e.g.
I don’t want to recreate what’s in those articles, instead I’m providing a short, sharp cheat sheet of the major topics you need to understand. So without further ado…
Sharing Cheat Sheet
Sharing Metadata Records
- “Object[Share]” for standard objects
- “Object[__Share]” for custom objects
- Fields: access level, record ID, user or group ID
- Share records are not created for for OWDs, role hierchies or the “View All” or “Modify All” permissions
- For Accounts, Contacts, Cases and Opportunities only.
- A platform feature, cannot be disabled.
- Access to a parent account—If you have access to a child contact, case or opportunity record of an account, you have implicit Read Only access on that account.
- Access to child entities—If you have access to a parent account, you may have access to the associated contact, case or opportunity child entities. Access is configure per child object when creating a new role.
Organisation-Wide Defaults (OWD)
- All standard objects use sharing access through hierarchies and this cannot be disabled
- Public (Read or R/W) can be seen by all users (including portal)
- Can’t be changed for contacts if person accounts are enabled
- All options are available
- Child objects have their sharing access level and ownership dictated by their parent. This also stands for any grandchildren. The parents value for “Grant access through hierarchies” is also inherited.
- Child objects don’t have a share-record of their own and will be shared along with the master record.
- In fact you cannot even define sharing rules from the object detail-page.
- Child objects can have their own sharing access level and ownership. Sharing access through hierarchies can also be disabled.
- Removed when owner changes
- Removed when access via OWD becomes at least as permissive as the share
- Private Contacts (those without an Account) cannot be shared manually
Apex Managed Sharing
- Can be used for Manual Sharing although it isn’t called Apex Managed Sharing in this context
- Using Apex to share Standard Objects is always considered Manual Sharing i.e. Apex Managed Sharing is only really a feature for Custom Objects
- Maintained across ownership changes
- Requires “Modify All” permission
- Need to create a class that implements the Database.Batchable interface
- The recalcuation is run when the OWD for the object changes
- The OWD for the object in question must not be the most premissive access level
Choosing the Right Share Type
“Traditional” / Ownership-based Sharing Rules
- You want to share the records that a user, group, queue or role own with another user, group or role (includes portal users with roles).
Criteria-based Sharing Rules
- You want to share records based on values of a specific field or fields with another user, group or role (includes portal users with roles).
Apex Managed Sharing Rules
- Your sharing requirements are batshit cray-cray. Examples include:
- Sharing multiple records at once
- Sharing records on object A based on criteria being met on object B
- Criteria-based sharing using a field not supported by “Criteria-based Sharing”
Manual Sharing Rules
- The record owner, or someone with modify all permission, wants to share an individual record with another user, group or role (includes portal users with roles)
- You want to share records owned by HVP users with internal users, groups or roles (includes portals users with roles)
- You want to “share” records with HVP users. These records need to fulfill the following criteria:
- Objects has an organization-wide sharing setting different from Public Read/Write
- Objects is available for Customer Portal
- Custom object has a lookup field to account or contact
High Volume Portals (Service Cloud Portals)
- Include High Volume Customer Portal and Authenticated Website profiles
- They have no roles and can’t participate in “regular” sharing rules
- You can share their data with internal users through Share Groups
- You can share object records where the object is a child record of the HVP user’s contact or account. This is done with Sharing Sets.
- They can also access records that are:
- Available for portal, and
- (Public R/RW OWD, or
- (Private OWD, and
- They own the record))
- They can access a record if they have access to that record’s parent and the OWD is set to “Controlled by parent”
- Cases cannot be transferred from non-HVP to HVP users
- Have a role hierarchy at most 3 levels deep and can participate in regular sharing
- Person accounts only have a single role
- Business accounts can have 1 – 3 roles.
Large Data Volumes
- Defer sharing settings (enabled by logging a case) and group calculation on large data loads and modifications
