Is there a reason why AX won’t display a simple note attachment in the job registration form? It seems like this would be the most commonly used type of attachment for conveying work instructions, etc. Is this something that is fixed in CU2?
What are you attaching the note against? Where do you want to see it?
The registration forms are designed to be single entry full screen screens for users to enter details, and not really AX functional. To deal with this the concept of the “Notice Board” was created for the registgration forms - have you looked at this?
