The numerical order of the existing documents is not kept. The re-numbering is done based on lexicographical order sorting.

When you have the following Document Nos in a General Journal:

Line 1: Document No = 1

Line 2: Document No = 2

Line 3: Document No = 10

Line 4: Document No = 20

and you then use the "Renumber Document Numbers" action, the lines will be re-numbered based on lexicographical order sorting:

1, 10, 2, 20

Expected would be that the sorting of the existing document numbers is not changed and it should be done based on the numerical order.

Document No 1 should be renamed to G00004

Document No 2 should be renamed to G00005

Document No 10 should be renamed to G00006

Document No 20 should be renamed to G00007
