Some background on the new ePick app is that it's only separate temporarily. This is because we're currently re-archtecting ePick completely and myWork 2.0 is not proceeding fast enough for us to build on it. So for now, it will be a separate app. Actually, it will always remain a separate app but next year it will live behind myWork so your entry point to ePick work will be myWork but in the backend, it will be a separate app. To TMs though, it will look and feel like it's all in myWork if that makes sense.
Also, on the comments for BR casepack picking vs. SF, etc... With the new backend ePick services, we changed how this works. It will allow for you to see SF locations for items previously you were only able to see BR locations for. So for example, with how the logic currently is, if you're picking an item that can be fulfilled by 1 BR location, and you skipped it trying to see the SF location, you won't see the SF location because the app forces you to pick from the BR location. Future, you will be able to see both the BR location and the SF location so if you want to skip the BR location, you can pick from the SF directly.
