Unmerge Process User Exits

Unmerge Process User Exits

The unmerge process can call the pre-unmerge and post-unmerge user exits.
The Unmerge SIF API calls the pre-unmerge user exit before the unmerge process starts. The Unmerge SIF API calls the post-unmerge user exit after the unmerge process completes.
The following image shows the batch unmerge process and the user exits that the batch unmerge process can call:
The user exits run within the batch unmerge process in the following sequence:
  1. MDM Hub
     registers the unmerge job.
  2. The pre-unmerge user exit runs.
  3. MDM Hub
     unmerges the records in the first block.
  4. The post-unmerge user exit runs.
  5. MDM Hub
     commits the changes.
  6. MDM Hub
     repeats steps 2 through 5 for the remaining blocks.
  7. The unmerge job ends after
    MDM Hub
     processes all blocks.
