starting number of system control
If we keep same as starting number of 11i (for example-100001), we cannot load historical asset with historical invoice numbers of 11i as Automatic numbering may skip some numbers.
If we keep starting number as 260001 (last number after historical migration) then I can load historical invoice number as asset numbers but then my last used number after migration becomes 520001 (260001+260000). So there is a gap of 260001 in numbering.
