Connectivity Editor

TARGET Reports supports a unique feature called variable connectivity. Once two or more variables are connected, they always have the same value. Reporting elements contain four variables that are available for connectivity: Input Data Source, Dictionary, Scope and Output Data Source. Let's imagine that your reporting document has multiple reporting elements, which get data from the same data source. Connect all those elements by their Input Data Source variables and, when time comes to switch to another data source, changing the data source for one element changes it for all. Another sample to consider is saving reporting results into a database table. Connect the Output Data Source for one reporting element to the Input Data Source of another reporting element and now you are able to use the reporting results from the first reporting element in the second for further reporting.

Click the Display Connectivity Editor button () on the toolbar or use the "View" main menu item to launch the connectivity editor.

Two tree panes (I and II) allow you to select variables to be connected. Pane III visualizes all connections for a selected variable.


 - Show all connections including the blocked ones.

 - Establish a bi-directional (<->) connection between two highlighted variables. Only variables of the same type can be connected. Having several variables connected to each other bi-directionally forces any change to one of the variables to be applied to all of the connected variables.

 - Establish a directional (->) connection between two highlighted variables. For the connection V1 -> V2 any change to V1 will applied to V2, but changes to V2 will have no affect on V1.

 - Establish a directional (<-) connection between two highlighted variables.  Same as  but in the other direction.

 - Block a connection between two highlighted variables. This operation is useful for the following case: connect V1 to V2 and then connect V2 to V3. As a result, V3 gets indirectly connected to V1.  If you do not want this to happen, you can block the V1 to V3 connection.

 - Disconnect the highlighted variable.
