Meta Entity Composition tab

The Composition tab helps you to describe and define the structure of the User Entities.

The Composition tab is divided into two panes:
  • The pane Composition corresponds to the composition lines tree that is used to manage the structure of the User Entities. You can add, delete a description, or move it up or down in the tree. In the composition lines tree, elements that can compose a User Entity are as follows:
    • Data Aggregate Descriptions Data Aggregate Description,
    • Data Element Descriptions Data Element Description,
    • Pac Data Elements Pac Data Element.
  • The pane containing the sections Data Aggregate Description, Component Usage and Data Element Description, corresponds to the definition of each composition line you have inserted or selected in the composition tree. It is used to specify the characteristics of the fields which compose a User Entity.
