Using the Delta Refresh feature
What do Delta Refresh updates do?
The Delta Refresh feature updates your inventory systems daily, when any direct or indirect changes trigger the system. Only the items that changed recently, called Deltas, are extracted and uploaded to Maximo Inventory Optimization. Deltas update items as new information becomes available from the ERP, such as stock on hand (SOH), and item description changes.
How often does the Delta Refresh run?
Delta Refresh updates run daily, sometimes more frequently, depending on what changes are triggered in the system.
How do I know whether the Delta Refresh update is happening?
When the Delta Refresh update is running, any items that are getting updated show an item state icon in the column next to the checkbox on the screen.
The Item State column displays two new icons for Deltas to represent when item is worked on by the Delta Refresh process in the background.
The two new item states are:
- Deleting This means that the item is going to be deleted by the Delta Refresh process.
- Refreshing This item is getting updated by the Delta Refresh process in the background. A refresh icon is displayed in the column next to the checkbox.
What happens to items about to be deleted by the Delta Refresh update?
When an item is about to be deleted by the Delta Refresh update, it is shown with a 
icon next to it. Items that are marked for deletion cannot be
actioned-edited, deferred, or approved. When the Delta refresh is complete, a prompt informs you
that the items can differ from what's on your screen and you need to refresh the page to obtain
up-to-date item information.
What happens to items refreshing by the Delta Refresh update?
When an item is being refreshed by the Delta Refresh update, you can make changes to the item, but you cannot commit the item when you use the 'End Session' function, only items that are not being used by the Delta Refresh update can be committed by 'End Session'.
In a Workflow situation, items refreshing during the Delta process cannot be approved or denied until the Delta Refresh is complete. When the Delta Refresh is complete, refreshing items become stale or in conflict if there's a change to a field that is not marked for auto update.
