Data Descriptor Structures

View name lists the available view names in the database and is the only field element that the user can manage. The list is usually retrieved from the BR_XML_VIEW table.

Note: For details about each element and its attribute definitions, see Business Rules Descriptors.

The database administrator inserts valid view names during the installation process. Construct using database is used to automatically create the field elements based on the view table definitions. Only the database administrator my use this function. Users can define field elements manually.

Each task descriptor has a unique name field that identifies the descriptor. The description field is optional and is not used in the XML that is created. The information in description field can be stored in the database for later use.

Note: For details about data types, see Business Rules Descriptors.

User Exit Classes is a special type of element that can identify user-defined objects.

Each element has an expand (+) and a collapse (-) link. Click expand and the application displays the available objects for the selected element. Clicking collapse makes all such objects hidden from the view. Attributes that have an asterisk (*) are required fields.

Field Element

At the right side of the field element table, click add new. The new element displays at the end of the list.

Users can manage the field element in either of the following ways:

Click Construct using database
Manually insert, update, or delete the fields

If the fields are defined using the database, the name, data type, and length fields are read only. However, users can still update the type as needed.

The default is empty fields. If required, change the values before saving.

Each element row begins with the function menu. To display available functions, click the arrow and choose one of the functions listed in Table 1.
