How to create share table record using Salesforce apex?

Hi Pranav,

To access sharing programmatically, you must use the share object associated with the standard or custom object for which you want to share. For example, AccountShare is the sharing object for the Account object, ContactShare is the sharing object for the Contact object. In addition, all custom object sharing objects are named as follows, where MyCustomObject is the name of the custom object:

MyCustomObject__Share

Objects on the detail side of a master-detail relationship do not have an associated sharing object. The detail record’s access is determined by the master’s sharing object and the relationship’s sharing setting. For more information, see “Custom Object Security” in the Salesforce online help.

A share object includes records supporting all three types of sharing: Force.com managed sharing, user managed sharing, and Apex managed sharing. Sharing granted to users implicitly through organization-wide defaults, the role hierarchy, and permissions such as the “View All” and “Modify All” permissions for the given object, “View All Data,” and “Modify All Data” are not tracked with this object.

Every share object has the following properties:

Property Name
Description
objectNameAccessLevel
The level of access that the specified user or group has been granted for a share sObject. The name of the property is AccessLevel appended to the object name. For example, the property name for LeadShare object is LeadShareAccessLevel. Valid values are:Edit
Read
All
The All access level can only be used by Force.com managed sharing.
This field must be set to an access level that is higher than the organization’s default access level for the parent object. For more information, see Understanding Sharing.
ParentID
The ID of the object. This field cannot be updated.
RowCause
The reason why the user or group is being granted access. The reason determines the type of sharing, which controls who can alter the sharing record. This field cannot be updated.
UserOrGroupId
The user or group IDs to which you are granting access. A group can bea public group or a sharing group associated with a role
a territory group if you use the original version of Territory Management, but not with Enterprise Territory Management
This field cannot be updated.

Thanks
