Document number & & already assigned (incorrect status in no.range &)

What causes this issue?

The number range from which the document numbers are to be assigned
displays an already existing document number as the next document
number to be assigned. This combination results from incorrect changes
to the number ranges.

System Response

The payment document cannot be created. Since further documents can no
longer be created with the same document type, this error results in
the termination of the program.

How to fix this error?

Contact your system administrator to correct number range &V3& in
company code &V2&. Then, restart the payment run with <LS>Edit ->
Payment -> After termination -> Continue</>. The remaining payment
documents are now created.
<ZH>Procedure for the system administrator</>
Determine the next free document number in number range &V3& for
company code &V2&. Use the <LS>List</> function for the document
display. For the list, predefine the company code, the fiscal year and
a document number interval. Use document number &V1& as the lower
limit, and the highest allowed document number in the number range as
the upper limit. If you add 1 to the highest document number which is
shown in the list, you get the next free document number.
<DS:TRAN.FB03>Proceed</>
Then maintain the number range with the <LS>Change status</> function.
<DS:TRAN.FBN1>Proceed</>
