Well it depends. Do you want it to come up automatcally and have the ability to change, or do you want to have to remember to make sure the comment is attached and also how long is this comment.If it is short then you could just add it to the supplier Remark field (2.3.1 in either SE or EE), then it will appear automatically into the remark field on 5.7 OR you can set up a comment with a name = to the supplier, and then make sure header comments is set to YES on the control file. This will then open a new screen during PO Entry and will display the comment = to supplier, but the use MUST accept this, if they back out first it wil not be attached. The biggest difference is the size of the comment (remark = 1 line, comments = almost unlimited). Master comments can be accessed at numerous menus. examples = 2.3.12 or 1.12. The advantage of the remark is it is controlled by only the people who can update the supplier, but comments are used all over the system so anyone with access to comments could change it.
