About this task

The following discrepancies can be identified and fixed:
Note: After you run the tool, you must save the module to save the changes.
The following discrepancies can be identified, but cannot be fixed:
  • Objects that exist in the history, but not in the current data.
  • Values that are recorded in history, but that are no longer valid for the attribute. For example, if the values associated with an enumerated attribute have changed, values in the history might not be valid.

The following discrepancies cannot be identified:
  • Changes to attributes and objects that were not recorded in the module history.
  • If OLE data was not included in the history record, it is not included in the updated attribute value.
  • If an OLE object was added to a text attribute that contained no text, and the object contains no text in the current version.
