The system cannot accept your entry.

Procedure
Please specify an allowed subgroup. You can then create an internal andan external number range for each subgroup.
The first two characters of a subgroup must contain a valid planversion. The next two characters must contain a valid object type.
Instead of specifying a specific object type, you can specify '$$' (='all object types') to set up a subgroup for all object types within aplan version.
You can specify '$$$$' to set up a subgroup for all plan versions andobject types.
You cannot specify '$$' for the plan version and then specify aparticular object type. Consequently, it is not possible to create asubgroup for all plan versions BUT specific object types.
