Salesforce Sharing and Visibility Certification Practice Exam

What is a probable cause for users seeing a Group membership lock error in the system?

1. Lock contention on Account records

2. Lock contention due to system-initiated sharing rule recalculation

3. Lock contention on Case records

4. Lock contention on Territory object

The correct answer is: Lock contention due to system-initiated sharing rule recalculation

Users may encounter a Group membership lock error primarily due to lock contention that arises from system-initiated sharing rule recalculation. This occurs when the system recalculates sharing rules and updates group memberships based on those rules. During this process, if multiple transactions attempt to update the same group or related records simultaneously, it can lead to contention. The system is designed to avoid inconsistencies by locking the records involved, which may prevent users from making changes until the locks are released. The other options focus on various record types, such as Account, Case, and Territory, but they do not directly connect to the context of group memberships and sharing rule calculations. Lock contention related to these other records may affect their specific operations, but the question relates specifically to group membership issues linked to sharing calculations. Hence, the focus on system-initiated sharing rule recalculations is the key factor behind the Group membership lock error.
