Dynamic values are the result of calculated data elements, and their values are only decided at run time. The values can then be used as parameters to other data elements (that run after, based on priority) or in action elements.
To use a dynamic value as a parameter for a data or action element
A screen appears with the list of currently defined data elements.
A symbolic reference to that data element is placed in the text field. The reference can be moved within the field, more text can be added before and after the reference, and additional dynamic values can be added too.
