Sometimes you may delete a Location but later realize that you need it.
When you try to add it in again you will receive a message telling you that there was a 'DB Update Failure':
This is because the location is still in the system but is in a 'Purged' state.
In SnapFulfil, when you delete something it is not immediately removed from the system. Instead it is marked as 'Purged'. It will remain in this state until the background services run and remove it from the database.
While it is purged, and before it is removed, you can re-instate it.
How to Reinstate
You can reinstate a Location by going to:
Master Data - Site > Warehouse and then click on the Locations tab.
Using the Magnifying Glass 
icon, search for a stage of Purge:
This will bring up a list of Purged locations.
Scroll down to find location that you require and highlight it:
The 'Reinstate' button at the bottom of the screen should become available:
Click Reinstate and then click Yes to the confirmation, the location will be available again.
