Sometimes, different planning areas are created to facilitate different functionalities. But login and logout is quite a pain in the butt. Here’s how you can do it easily by opening up a new Excel instance.
For Opening Up another Excel Instance, Hold you ALT key, then click Excel (**remember to KEEP holding it until you see the window: "Do you want to start a new instance for excel?". After that you can release the ATL key)
Check PA info
Repeat the same process and login to a different planning area
