Transfer static
Constants are available as a data source for fast configuration of “static” values. In contrast to variables, constant objects only apply within the connection in which they are configured. Constant objects can only be set at design time, not changed at runtime.
If a value is too long, you will be asked if you want to cut off this value. If you click “Yes”, the value is truncated to the maximum length of 255 characters. If you click “No”, the dialog remains open and you can select a new value.
Create a constant transfer object within the connection as explained.

Constant Transfer Object
After double-clicking on the transfer object, set the following properties:
Value | Any value |
Type (after click on “Expand”) | (optional) Data type |
