Q: Is it possible to customize Item Placement Tool to each user?
A: Yes. Each configuration can be set up to be used by specific users.
Q: I have added a bunch of user-defined fields onto the main window from the sidebar but the fields are now both in the sidebar and onto the main window
A: The is normal SAP behavior. The things we add to the main window are only copies of what is on the UDF-sidebar. If you do not wish to show this data you need to close the sidebar entirely or hide the sidebar fields (standard SAP functionality using CTRL + SHIFT + b when you are in one of the sidebar fields)
Q: Is it possible to move tabs using Item Placement Tool?
A: No. This is not possible due to limitations in the SDK
Q: It seems to be impossible to hide entire tabs on BP Master Data. Is this a bug?
A: This is a known issue. Item Placement Tool can hide entire tabs, but there is an issue doing it on the BP Master Window. This is due to the fact that in Find mode a BP Master Window shows only x tabs while in add/ok-mode it shows x tabs. This means that SAP allows hiding tabs initially but then turn up again when you browse/change mode (SAP “un-hides” them). We have been in contact with SAP support on this because we think this is incorrect behavior as no other window show/hide tabs on the fly, but they will not change this due to backward compatibility. Therefore it is possible to hide tabs on all windows except BP Master Data.
This is also the case for other types of functionality like MassHide in the macro system.
Q: Does the SAP UI Configurator and B1UP work together?
A: It's not recommended as UI Designer is rather disruptive to add-ons. So on a screen, it is either all Boyum or all SAP.
