Displaying the Sequence of Source Documents 
Prerequisites
The document that you are currently processing was created with reference to a source document.
Procedure
- On the Document data tab page, choose the function Extras → Sequence of sources
The Sequence of Sources screen appears.
- The document you are currently processing is in the lowest line of the list, with the highest sort number.
- If this source document was also created by copying from another document, you see this source document, too. The source document is always in the lowest sort number in the superior line.
The first document that was created without copying is shown in the first line, with sort number 001.
- Go back.
