SAP Message >0005 - No free number range found for document type &1

Diagnosis
The document type you are using is used for a mass processing sessionthat runs in several parallel processes. A separate number range isrequired for each process. The system has been unable to find a freenumber range, the reason being that there are more processes active thanthe permitted number ranges available.
A number range that is at least 98% exhausted is no longer used toensure that there are sufficient numbers for mass processing.

System Response
Processing is terminated.

Procedure
Assign further number ranges for mass processing to this document type.
If there are sufficient number ranges but some of them are already 98%exhausted, increase the assigned number range. If this is not possible,assign a new number range.
Make sure that you select number ranges large enough that the documentvolume for several years is covered.
