How do you go about breaking the link on one of the G revision on the right. I would like to put ECO number there, when I put ECO number there, the whole 'G' changed to ECO number.
It sounds like the rev history table things that column is the revision. Have you tried putting the ECO number in and then going into your custom properties and changing revision back to "G"?
Also, make sure you don't have the Auto Update Zone Cells checked (Unless your company usually uses it.)
I'm sorry, I don't have a better answer on how to prevent this.
