You have the following option for assignment:
Take your long-term needs into account when defining your number ranges.
You transport number range objects as follows:
In the initial screen, choose Interval -> Transport.
Note that all intervals for the selected number range object are deleted in the target system first. After the import, only the intervals you export are present. The number statuses are imported with their values at the time of export.
Dependent tables are not transported or converted.
You should use internal number assignment.
Since you can select networks using a matchcode for different criteria, it is generally not necessary to use numbers you assign yourself.
Maintain the number ranges for the network.
