Silent metadata synchronization
When we use the Microsoft Dynamics AX command line parameters to trigger a startup command with running the client, it is a very common situation that our metadata is altered.
There could be many scenarios where the metadata change requires user interaction (like a possible index violation, removing fields, etc) on a form, where you could review the changes before it is permanently committed to the database. This is not ideal if you would like to do automated tasks, like running a workflow step on a Team Foundation Server build controller (code / metadata synchronization, XPO import).
Fortunately there is a way of suppressing this user interaction, by setting a global variable.
