Accessing the list of available classes and underlying field details.

In the SAP Ariba object model, each field is classified as safe or unsafe. Only safe fields can be used for customization purposes. When you access a class and expand the Fields section, only safe fields are shown by default. You may uncheck the Only Show Safe Fields to see all fields for the class.

Some classes have methods defined to serve special purposes. Some of those special methods are documented in the Methods section within the Class Browser.

Templates are used to add or remove fields from interfaces or define proprieties of fields. Each possible template is listed in the Templates section of the Class Browser. Templates are covered in more detail later in this course.

If Normal custom fields can be created in the class, the Unused section in the Class Browser is expandable and shows the pre-defined pool of fields that can be used to create new Normal custom fields. The Info column indicates how many Normal fields are currently available and have been used for each type of field in the class. For example, a maximum of 26 Normal String fields can be created on the Requisition Header; if 1 has been used, 25 remain available. If the desired field type has been fully depleted, consider using another field type that is suitable for the requirement. For example, if you run out of Boolean fields then you can create a string field with an Enumeration that has values ‘Yes’ and ’No’. Keep in mind, Computed fields don’t consume from this pool. The concept of Normal vs. Computed fields is covered in more detail later in this training course.

• An arrow is displayed beside the column header that is controlling the display order. You can change the display order by selecting the column header Field, Info, or Type.
• The table menu provides additional options, such as Expand/Collapse All and Export to Excel.
