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: This 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 the 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 (or Item Master Data starting from SAP10). 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/Item Master Window. This is due to the fact that in Find mode a BP/Item 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/Item Master Data.
This is also the case for other types of functionality like MassHide in the macro system.
From SAP10, this also affects the Item Master Data form.
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.
