Hi mkwendt
Thanks for your post.
We haven't come across a similar situation before where the purchase order numbers are skipping forward so many numbers in between. I would recommend clearing the AccountRight cache and if it still happens, please confirm the following:
1) Do you use recurring transactions? If yes, does the problem occur if you do not use recurring transactions?
2) Does this happen even if there is only one person using the file?
3) If you manually override the numbers, does the sequence continue or still skips to random purchase numbers?
Let me know how you get on with this.
