Wildcard to identify all inventory orgs based on last character

Summary:

I want to find a wildcard character that will allow me to find all inventory orgs to associate to an item based on the last character.

Hi,

My client's inventory organization codes are all based on last characters that categorized them (ex.: ABC_W, ABC_H). We want to identify all inventory organizations that end with W, or H for example. Doing %_W worked in previous environments, but is not working anymore after an update, for some reason. We use this in the item organization associations tab.

Does anyone know of a wildcard character that I could use to identify all inventory orgs ending with W?
