Hi, I have a MR script which sets 5 custom line fields on a pre-existing Sales Order. Four of the five changes are recorded in the Line System Notes, but the 5th one isn't. It's a regular stored free text field, and if I edit it in the UI that is recorded. Any suggestions?

Is it possible setting one of the 4 fields resets the fifth and you're setting one of the four after the 5th you're talking about?

No they are unconnected. Looks like it only happens when the field is initially null. Changes ARE recorded.
