Number sequence - block defined numbers

Hello @all,

is there a way in AX2012 to define a list of numbers which can't used in the number sequence. E.g. our customer has on production order a number sequence ######, means from 000001 - 999999 but he don't want to use the following ranges:

150000 - 299999
400000 - 449999
800000 - 999999

Any idea how to handle this without a lot of programming?

thx in advance,

Wolfgang
