I created an automatically generated ID with this syntax ORG_UNIT_CODE(…)-SEQUENTIAL(#####) and noticed that even though it works, it does so in increments of 2, not 1 as stated in the documentation.
Thank you once again and from my post, this is what I have done. The plus or the minus sign does not make a difference from what I have tried and both give the same results and the same output. Both methods increment by 2 instead of 1.
