Currently when you modify a Work Order that already has an SPM-MTTR record, the existing MTTR record is updated and the labor time from the Work Order is added to the existing MTTR record.
Rather than adding to it and doubling or tripling the Labor in minutes, the MTTR engine should replace the existing value or should automatically update the Labor lines it has already picked up so the time is not added the existing MTTR record.
Also if a mass update is done to thousands of Work Orders the MTTR data associated with those records will be doubled, assuming the work orders fall into the window specified in SET002 (Org-wide configuration | Service Performance Metrics | SPM Configuration).
What is the underlying problem do you intend to solve with this idea?
Preventing MTTR data from becoming inaccurate due to simple updates after the MTTR record has been created.
How is the problem being addressed today, if at all?
Reviewing and manually updating the MTTR data each week
