Many D365FO users work with multiple legal entities at one time. For years the AX/D365FO design has assumed that a user is only going to work in one legal entity at one time. This is no longer true as Microsoft has pushed the software to meet the needs of larger and larger customers. Legal entity code is really just another dimension. That's the way all my clients have treated it. Having the LE code govern everything on the form limits larger customers. Please move legal entity code down in to the data on the forms where it belongs and out of the window frame.
