I want to make the amount of text in description larger. I Have created a new Feild which i can add to the form and make required, but I can't see where you would change the current one either to make it bigger or remove it?
The default 'Description' attribute is of size 80 characters and it cannot be changed. However, as you have already implemented, you can create custom fields and make it mandatory.
FYI, remember one thing. The default 'Description' attribute is a global field, meaning it appears in almost all the other modules. If you change the name of this attribute, it gets changed in all the modules. These global attributes help while copying the records. There is no option to create such fields in OVSD.
you say you want to remove the current description field...then what is to stop you from dragging it off the form...or right click and Remove the field description (of course I am assuming you have removed it from being Required)
