Hello, 

When we unissue component material from a shop order we do not want to unissue back to the original location. Instead we ask the production associates to unissue to a location under a specific location group and the Location to Unissue page. I would like to create a custom event to validate that the user is selecting the appropriate location group when unissuing from shop order but I cannot seem to find the correct logical unit to use. Any ideas?
