Hi @olgatrykush ,
Thank you for your quick respond.
But I would like to point out that it is not about the ID (=row_id) of the rows.
row_ID as in in column 1 on the left side in my screenshot.
But it is about a Autonumber field. The second column in my screenshot.
As I wrote: it doesn’t not only skip any numbers. It started “back” at an earlier number (after moving the instance).
So for my understanding this is a separate issue(?). And regarding that, I’d like to come back to the questions I mentioned above.
