Thanks for the reply,
Is it just the SYS:Menu Items where you have to modify the field or all the forms such as the Worklog form, interface form etc. I have found 4 different forms with the work info type and it looks like you have to modify each manually in addition to the SYS:Menu Items form.
Do I have this right or if the hidden field are modified on the SYS:Menu Items form all the other forms are also modified?
Thanks for your help.
