In the Production order maintenance screen the inspect element shows the DataView - LSAMProdItem_lotseropts on the APSX page used as DATAMEMBER for the tab
But on Graph this data view is not defined,
How can I get to this Dataview???
This is a special view, generated in code, inside the specialized view declaration
public LSAMProdItem lsSelectItem;
The logic is in LSSelect which is the base for LSAMProdItem class, and looks like this (where in your case, in production order, this is the LSAMProdItem object):
graph.Views.Add(this.Prefixed("lotseropts")...
