Object that represents a hierarchy level in a format tree structure.


Nodes are used to model a file defined by a certain external authority, such as a bank, government, or standardization organization. In most cases, it is possible to transfer to the format tree on a 1:1 basis the structure in the file description that the authority provides. SAP recommends that each file field corresponds to an element in the format tree.


Each format tree begins with a root node called the header. It appears automatically at the top of the tree structure when you create a format tree, and you can maintain the details on the right.

Below the header, you insert nodes to form the body of your format tree based on your file requirements. Likewise, details for the nodes can also be maintained on the right. For a description of the nodes and when to use each type, see Node Types.
