Final answer:
Apex managed sharing in Salesforce allows administrators to manage record access. To recalculate Apex managed sharing, you can use the 'recalculate sharing' option or programmatically through Apex code.
Step-by-step explanation:
Apex managed sharing in Salesforce is a feature that allows administrators to manage record access across different users and roles in an organization. It enables customization of the sharing rules according to the organization's specific needs.
To recalculate Apex managed sharing, you can use the 'recalculate sharing' option in the Salesforce user interface or programmatically through Apex code. This recalculates and updates the sharing rules based on changes made to user or role permissions.
An example of how to recalculate Apex managed sharing programmatically using Apex code is:
- Create an instance of the 'ApexManageSharingRecalculation' class.
- Use the 'recalculating' method to perform the recalculation.
- Handle any errors or exceptions that might occur during the recalculation process.
