Hi Bijay Sir,
thanks for reply,
What I understood is
You can maintain number range year-wise but with different interval for particular group like
9999 | 100000000 | 199999999 | 100045491 |
2013 | 200000000 | 299999999 | 0 |
2014 | 300000000 | 399999999 | |
but my requirement is having same interval for different years
9999 100000000 199999999 100045491
2013 100000000 199999999
2014 100000000 199999999
But the thing is that system wont allow me to maintain number range for 2013 and 2014, until year 9999 entry is there for a same interval, so I deleted that entry and created following no range and assigned the last number range to year 2013
2013 100000000 199999999 100045491
2014 100000000 199999999
will deletion of 9999 existing entry create any problem in the business.
