In Simple Maintenance, the different elements in an organizational plan are visually represented by a tree. The different branches illustrate the relationships among different objects. The tree structure is not just a presentation tool. You can also use it to build and maintain plans with speed and simplicity.

The tree structure presents clear advantages for maintaining plans. You can:

• Visually perceive relationships between the different objects
• use the system to create certain relationship records based on where you place objects within the tree structure
• Select the objects you want to work with by selecting them on the screen. (To select objects in Infotype Maintenance, you must provide object IDs)
• move objects within the structure by choosing them on screen

You can adjust the tree structure display so that it shows different types of information. For example, you can adjust it so that it displays validity periods for objects, or for relationship records.
