How to fix this error?

If no mapping for the company codes for number assignment is maintained,
the target company code will use the company code for number assignment
of the reference company code. It is possible to rename company codes
for number assignment (for example to keep the same naming of company
code and associated company code for number assignment). It is also
possible to map several company codes for number assignment to one.
In this case, all company codes which have the source company codes for
number assignment are after the conversion assigned to the target
company code for number assignment.
If several ones are mapped onto one, the one with the reference
indicator would inherit its number range definitions. The source company
codes for number assignment would be removed unless they are the target
company codes for number assignment.
