Hi all. I had a mysterious issue occur where a transaction group ceased recording data somewhat randomly. I can confirm that the transaction group was working prior, and that no one on my team made edits to the transaction group at the time. It is set up in MSSQL in a table which has an auto incrementing identity column (used many times with no issues), however when I went to look at the messages on the transaction group all I found was an error saying I was missing a required column which is Ignition’s custom index column that apparently it was trying to record to the database (see screenshots of messages and group configuration below). All I did to get the group to work again was to disable the group, save, re-enable the group, save again. After this and no other changes the group started working again. Any ideas? Thanks!
