Creating Relationships Using the Graphics Function 
A screen appears which displays all the operations you have previously entered for the order.
The system links the two operations with a line and writes in the type of relationship. The line always goes from the right-hand edge of the predecessor to the left-hand edge of the successor. In other words, it only shows that a link exists; the type of relationship is shown above the line.

Once the first relationship has been created, the system automatically adjusts the scheduling for the order. The system informs you of the change in an online message.
Make all the required entries.

From the graphic, you can call up the detail views for internal and external processing of operation data, enter or change the data and then return to the relationships graphic.
You can also create new operations using the graphics function. For more information, see Creating Operations for Relationships Using the Graphics Function.
