You don't have a license for optional fields, you need to purchase it.

There is no "reference document" for this, because the error is self-explanatory.  You don't have a license for optional fields.

Hi Jay ,

   I can't understand what do you mean by optional fields ?

Thanks

Talk to your business partner, this is a very, very basic part of Sage licensing.

Thanks for your reply
