What happens if an 'all users' lock date is set in the depreciation period?

When an 'all users' lock date is set in the depreciation period, it effectively prevents any changes to transactions within that period, including running depreciation. Thus, you cannot run depreciation for that specific period because the lock date is set to maintain the integrity and accuracy of financial records by stopping any alterations that could affect reported figures. By locking the period, the system ensures that prior transactions remain unaltered, which is critical for accurate financial reporting and compliance.

The other options suggest that either depreciation calculations would be adjusted, incorrect, or allowed without posting new entries, all of which do not align with the function of a lock date in financial systems. The lock date's purpose is to preserve the state of accounting for that period rather than allowing for modifications or approximations.
