The Header of a component is its most important attribute.

Function

• The Header defines the name of the database table/view field with which the component will exchange information unless the component is part of a transposition.
• The Header of a component is a unique identifier within the containing branches: root/pattern or root/multi-tab or root/multi-tab/pattern

Uniqueness of headers

Two components can have the same Header if, for example :

• they are in two different patterns
• they are in two different multi-tabs
• they are respectively in an independent pattern and multi-tab, the pattern not being in the multi-tab

Two components cannot have the same Header when, for example

• one is part of the root
• one is part of the multi-tab (outside the pattern) and the other is in a pattern of the same multi-tab

The uniqueness of headers is checked during an Excel import into Design. The uniqueness is checked after the import and a dialog box warns you of the presence of duplicates and prompts you to view them for correction. If you refuse, it will not be possible to save the document.

• You can use the Tools Check Header Uniqueness function at any time

Syntax

• Headers are case-sensitive. For example, Edit and EDIT are two different headers.
• A header cannot contain control characters (ASCII code < 32) or any of the following characters: , ; ! ? ” ` ^ ¨ ~ ° ¤ [ ] { } |

Use of the Header in Design

The Header is used to designate the source of a drop-down list or the source for item selection when adding a tab in GTAnswer.

Exposing a clear label to users

The Header will be exposed to users when attempting to transmit a response for a form with at least one mandatory component not filled in.
However, the Header is often not very “meaningful” for a functional user, either because it uses the database naming convention or because it is very long (this is particularly the case for components included in a transposition).
In this case, it is advisable to use the “Display name” property of the component, making it possible to assign a functionally explicit label to a component.
