Application Builder has small images (icons) each representing a node type. For example, node types represent BOM levels in TPM. You build product structures in TPM using these node types.
Triniti supplies standard images that represent node types (BOM levels, enterprise, factory, and so on). You can, however, upload custom images that represent node types in your organization using the Application Objects module.
Application objects module is also used to generate numbers automatically. The automatically generated numbers will be used in assigning property values for nodes in the TAB applications. These numbers are alphanumeric.
