Q: Is it possible to customize Function Button for each user?
A: Yes. Each configuration can be set up to be used by specific users.
Q: Can the buttons be moved to another location than on the right side of the screen?
A: Yes, you can use the Item Placement Tool to move the buttons
Q: When I add a function Button configuration to my screen it stops remembering its last opened size. What is wrong?
A: This is a know limitation of the SAP SDK in that whenever you add a button we need to increase the width of the screen to display the buttons. Manipulating the width/height of a screen via the SDK have the limitation that it then can't apply the last remembered size. The workaround for this is to make the button via Item Placement Tool (B1UP2016.10 or later) or the Content Creator and then use a B1 Validation System config to add the action of when the button is pressed. The drawback of this is that B1UP can't set room for the button and you need to place it in some of the existing space
Q: Is there an alternative to buttons? (they take up space)
A: Yes, you can do the same as Function Buttons can do with the Right-Click Menu creator module
Q: I have a scenario where when function buttons are added I can't see the SAP buttons on the lower left and the scrollbar is missing to get to it. What is wrong?
A: This is a known issue. the SAP SDK can't both at buttons and keep the scrollbars at the same time :-( So in order to use. For more info see this article
