In Miscellaneous Item Maintenance, you can define a Comment Type and use if over and over.  As an example:  ABC and Type = Comment.  Add in the comment you want to print on your sales orders.  When entering in the sales order, add /ABC and it will populate the comment on a line.  You an edit or modify the comment once it is added to the sales order line. 

Memo?  Or comment line text?

In miscellaneous item maintenance you can add comments like /TERMS, where the comment text is pre-configured.  Then you just add /TERMS (or whatever you call your comment code) to a line, and it brings in the comment text.

Is the comment based on the item being purchased on the PO or by the vendor selected? If the comment is standard you can create a misc. comment and add it to each PO or you can use crystal to add the statement if a certain item is purchased or if a specific vendor is used. 

The easiest way is to use the misc comment as crystal can be hard to work with if you are not familiar with it. 

You could also create a GO BY PO that has all the comments you would like and use the copy from function?

If I have multiple Misc Item Codes is there a way for people to see a list of the codes without having to memorize them or go to the Misc Item Code Maintenance?

When entering an order if they press the "/" key and then F2 it will pull up the list
