What is the purpose of the Notes field if I cannot enter a note?

As I understand it, the Notes field on an overview list/table like this is typically just intended to show the Note that was entered as the transaction was done (i.e. a Note made during the transaction).  Same way you can see the timestamp but cannot modify that either. 

​@NickPorter the problem is on many transactions such as Unissue Material there is no place to enter a Note, thus no information gets stored in the Notes field. The user enters the info, clicks OK or Save and that’s it. 

I would guess (and that’s all it is) that the Notes field is coded as a standard field for overview tables, so that it can be used to show data if the underlying objects actually have Notes in them, and in this case it doesn’t.  It would be interesting to know if that Notes field was enabled by default for the screen or if it was manually added using the column chooser… that might help validate my thinking.

We’re not on the same version so I cannot check it myself.
