The list of course can be found at: CA Technologies Global Search Results
For "Select a Catalog" - Pick your country where you want the training to take place.
For "Product" - Select "Automic Workload Automation" -I know you are looking for "AWI" but that is a component under the product line "Automic Workload Automation"
Please note the result my varies depending on where you are located, but if you are looking for that particular AWI course training (if you do not see it on the list - your CA/Broadcom sale representative contact would be able to help or if you don't know who they are, I can help in find your sale representative to contact you if you like).
