Hi Marco,

As Carlos said, its not possible to have multiple default values on a parameter (in case you are referring to using the DefaultValue element as described in DefaultValue element | DataMiner Docs)

However, you can hardcode all possible values in C# (via a QAction) and trigger that QAction during startup. Based on certain conditions (e.g., other parameters), you can set the desired value programmatically.

There are several ways to trigger a QAction (timer, button, etc) so this will depend on the use case

Kind regards,
