Goal
Add the same product to a group of locations at once, or remove it from them, without opening each location one by one.
Who
Office Manager or Org Admin.
Steps
On the Field home page, use the checkboxes to select the locations you want to change. To act on every location that matches your current filters, use Select all.
In the action bar that appears, choose Add Material or Remove Material.
Search for the product and pick it.
For an add, choose whether it's a part, tool, or equipment and set the min and max quantities. For a remove, confirm the product to take out.
Submit. The change is applied to every selected location.
Notes
Select all follows your current filters (Office, tags, and so on), so you can target a whole tag or Office in one pass. Any rows you've unchecked are left out.
Removing a product takes its bin out of the selected locations; it doesn't erase the location's history.
