Double-click the Start of user-def. text field to open the long text editor.
You can format your text. When the text is printed out on a report, all formatting (character formats, paragraph formats, and so on) is retained. The prerequisite for this is that the environment parameter LONGTEXT_FORMAT_SUPPORT must be set in Customizing for Product Safety.
Choose Back. If your text is longer than 132 characters or you have formatted it, the Start of user-def. text is grayed out. You can then only edit the text using the text editor.
