Sometimes additional link information is useful when you link a document with an SAP object. You can maintain an information text for every link between the document and an SAP object (for example, customer DEBI-US51).
You can maintain the link text in either the document info record or in the master record for the object (for example, customer DEBI-US51). The long text is maintained with the PC editor and saved in the text database.
You have linked the document with at least one object (for example, customer DEBI-US51).
On the Object Links tab page, choose the Create pushbutton in the Long Text column for the relevant object link. Enter your long text and then save the document.
