In this tab, you can organize the description fields of
a User Entity or of an entity that is extended by a Meta Entity Type.
You can also enter their values, which must conform to the components
descriptions of the related Meta Entity.
About this task
There are several possibilities to enter the description
fields. You can either add all the fields in a data description, or
add the fields one by one. You can also enter the required fields
only with a cardinality
1-1.
Procedure
- Open the description tab of a User Entity or a of an entity
that is extended by a Meta Entity Type.
- If the structure table is empty, you must do one of the
following actions to complete it:
- Insert all the fields at once. Click Add all Fields to
duplicate the structure that is defined in the Meta Entity. The root
data aggregate is then displayed at the top level of a tree structure.
The other data aggregates are displayed at lower levels.
- Insert the fields one by one as follows:
- Click Add Field to display the root data
aggregate.
- Click Add Field again. It opens a selection
box in which you can select a component to be inserted in the User
Entity.
- Click Add value. Then, click either Add
all Fields to add all the fields that are defined in the
Meta Entity for this data aggregate description, or click Add
Field to select a field in the selection box. If mandatory
fields are defined in your Meta Entity, click Add Required
Fields to add them. If they are not added, an error is
notified.
Note: You can duplicate a data aggregate and the fields it
contains by using Copy and Paste in
the contextual menu.
- Enter values that fit the description of the Meta Entity
to prevent errors. To do so, click the field and then the value column,
and enter a value.
- A table is displayed in the Description detail section
for each data aggregate description that contains multiple values.
Simple fields only are displayed (integer, decimal, date, string,
float, byte, time stamp, reference with a maximum cardinality of 1)
in the data aggregate description. Each column corresponds to a description.
If you click a column cell, the default value that is indicated in
the Meta Entity is displayed. However, it can be modified by entering
another value or by opening a dialog box for longer values. Click + to
add other lines in the table or − to delete
them.
