TBB1 posting error : CO number range exhausted

Hi,

Recently we came across a case where the CO number range were exhausted. This affected postings in various sub modules including treasury.

When i searched i couldnot find any blog for this but only some discussions hence summarising in total to help others.

The below are the possibilities of resolution in KANK :

If there is no overlapping with other number intervals, you can simply increase the value for the interval upper limit. Number assignment is then continued at the current number level – In our case it was not possible as we have overlapping number ranges but this solution might help others.
Assign the transaction to a different number range group in which the number interval for internal number assignment has not yet been exhausted. The next document number is issued from this interval. – we had no group in which number ranges were not in use hence created a new one as below.
Create a new number range group with an interval in which no CO documentnumbers have yet been issued. Then, assign the transaction to this new interval.
