CAUTION: Critical reuse of already used object lists

What causes this issue?

While attempting to determine a new object list number (number range
object &V1&), the system determined that the number has already been
assigned.
This is the case when the number range interval has already been
exhausted, and due to the 'Rolling' setting, the number level has been
reset automatically or the number level (NR status) has been set
manually by the system administrator to a lower number than those
already assigned.

System Response

Processing is terminated to avoid inconsistencies.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Procedure for System Administrators

Check the number range object <(>&<)> and the number level. Transaction
IP22.
Situation 1:
The "To Number" is set to the standard SAP value "0999999999".
In this case, the following steps are recommended:
- Set the "To Number" to "1999999999".
- Set the number level to "1000000000".
Warning: Never set the "To Number" to a value higher than
"2147483647".
- STRONGLY RECOMMENDED: Develop a concept for archiving the existing
"old"
object lists so that the situation that just occurred does not occur
again.
Situation 2:
The "To Number" has already been adjusted and is set to a value between
"0999999999" and a value much lower than "2147483647".
The system administrator has already reset the number level to a number
level already used, or the number range object has reached the end and
the 'Rolling' setting caused the number level to be set to a number
level already used.
In this case, the following steps are recommended:
- Note the "To Number".
- If possible, set the "To Number" to a value much lower than
"2147483647", or if not possible,
set to "2147483647", because this number is the maximum number
technically possible.
- Set the number level to the noted "To Number"+1.
- VERY STRONGLY RECOMMENDED: Immediately start archiving for the
archiving object PM_OBJLIST to delete "obsolete" object lists from the
system so that they can be reused and to prevent the situation that just
occurred.
Situation 3:
The "To Number" has already been adjusted and is set to the value
2147483647.
The system administrator has already reset the number level to a number
level already used, or the number range object has reached the end and
the 'Rolling' setting caused the number level to be set to a number
level already used.
In this case, the following applies:
- Archiving must be carried out for the archiving object PM_OBJLIST.
- After archiving is completed, the number level can be set to the
"start value" of the archived object lists.
