Error when creating a Number Range

Question

When I use transaction ZNRO to create a number range, I get an error message:
"Invalid call sequence for interfaces when recording changes".
All I did was enter the text and a domain for the numbers.   There was an earlier error regarding buffering.  It said that I should not use buffering for accounting documents.   I am not using this for accounting documents and do not care if numbers get skipped.  So I continue through that error. 
But after that, the "Invalid call sequence . . ." error pops up.
I searched this forum generally, and with portions of the error text, and do not find any discussion of problems creating number ranges.
The number range I'm created is very simple.  I just need "one up" numbers for a custom database used to store custom schedule information.
I'm at release 4.6c.

Answer 1

Here is the error message and text.
I have no idea what it means by "interfaces".
When at release 3.1i, I had no trouble creating number ranges.
<b>Message no. TK 425
Diagnosis
The function you selected uses interfaces to record changes made to your objects in requests and tasks.
Before you save the changes, a check needs to be carried out to establish whether the objects may be changed. This check must be performed before you begin to make changes.
System Response
The function terminates.
Procedure
The function you have used must correct the two Transport Organizer interfaces required. Contact your system administrator.</b>
