What is the correct order for cancelling three different processing sets if global or custodial deduplication is selected?

The correct order for cancelling three different processing sets when global or custodial deduplication is selected is to do so in reverse order. This approach is essential in scenarios where deduplication has been applied, as it ensures that any dependencies or relationships established during the processing of the earlier sets are appropriately handled.

When deduplication occurs, the last set processed may contain references or links to items in the previous sets. By cancelling the processing sets in reverse order, you prevent any disruptions that might arise from prematurely removing a set that still has interdependencies with later sets. This way, the integrity of the data is maintained, and any potential issues caused by cascading effects of cancellations are minimized.

In contrast, cancelling in a sequential, random, or immediate order could lead to inconsistencies or data loss, particularly in complex environments where data relationships are significant. Therefore, following the reverse order for cancellations helps maintain an organized and stable processing environment, which is critical for effective deduplication and data management.
