Field help (MGGTGPNUM) 

This field is used to indicate the local preference for the presentation support. By default, the presentation support suggested by the system is by order of priority:

1 / The user's personal preference for the support defined for the target entered.

2 / The presentation support associated to the target.

This field also has available a contextual menu named "Default personal preferences". When using this menu, the user sets his/her permanent personal preferences in terms of presentation support for the current target. This way, the same presentation support will always be suggested by default when creating each new target defined by this user.
