Hi and many thanks,

Unfortunately the system is already done and therefore no modifications are allowed.

Yes, the example is only just to show the complexity, but the real system is very articulated with the chance to make chains (hierachies) connected to each other.

So there is not a schema predifined.

I understand that to include a real example should be better but:

1) I cannot disclose information

2) The Hierarchy are so articulate that are difficult to present as example.

Kind regards.
