Auto numbering skipping numbers

[mrcarter]

I have a table that is an extension of the CMDB_CI table.  I want auto numbering to exist.  When I try to do this auto numbering always skips by a one number.  Why is this is the case and what can I do about it?

You can use the property mentione din the link beloe to ensure that there are no gaps(global change)

Numbers are generally skipped because a number is allocation but the record is not saved. See if anything like this is happening in your instance.

I am told because CMDB_CI is auto numbered and my new tables takes the u_number field form there that the numbering goes up by two???

This doesn't justify.

Incident is also child of task, doesn't mean it should skip numbers.

Did you speak to HI for this?
