>Actually, changing MIN() to MAX() resolves the issue. I just tested it. Out of those 2002 records, they represent in fact only 56 RO. In the RO table, there are 56 records. So, the process took 6 loops (10x5) and one last one with 6 records.

Are you sure it did? E.g. you do need to use MAX, of course, but who will guarantee you will not get the same RO_NO again after your robot processed 10 records?
