The ID gives the full path to a block through the hierarchy of sub-systems that contain it.
The ID consists of the name of the block and the ID of its parent sub-system.
For example, with a hierarchy where the sub-system _France_ contains the sub-system _Paris_ which in turn contains the expression _Price_ their ID's are:
Type | Name | ID |
---|---|---|
Sub-system | France | France |
Sub-system | Paris | France.Paris |
Expression | Price | France.Paris.Price |
The ID of an object must be unique in the project.
