Enable Manual Account Sharing in Enterprise Territory Management (Critical Update, Enforced)

Enable Manual Account Sharing in Enterprise Territory Management was a critical update in Spring ’19 and is enforced in Spring ’20. This critical update changes the TerritoryManual reason code in AccountShare records to Territory2AssociationManual and is required to let users share accounts manually with territory groups.

Where: This change applies to Lightning Experience and Salesforce Classic in Performance and Developer editions and in Enterprise and Unlimited editions with the Sales Cloud.

When: This critical update is enforced in the Spring ’20 release.

How: If you have Apex code or integrations that work directly with the AccountShare object, make sure that you update all instances of the TerritoryManual reason code to Territory2AssociationManual.
