Showing or hiding realized <viewpoint name>* Exchanges

You can choose to either show or hide the conveyed <viewpoint name>* Exchange Item on the element realizing <viewpoint name>* Exchanges.

To show/hide the realized <viewpoint name>* Exchange Items

1. On the diagram, click the element for which you want to show or hide the realized exchange.
2. In the smart manipulator toolbar:
   1. If the <viewpoint name>* Exchange Item is not displayed, the tooltip for the button is Show Realized <viewpoint name>* Exchanges. Click it to hide the <viewpoint name>* Exchange Item.
   2. If the <viewpoint name>* Exchange Item is displayed, the tooltip for the button is Hide Realized <viewpoint name>* Exchanges. Click it to hide the <viewpoint name>* Exchange Item.
      If the element realizes only one <viewpoint name>* Exchange, the <viewpoint name>* Exchange Item is displayed/hidden instantly with the click of a button.
      
3. If the element realizes multiple <viewpoint name>* Exchanges, the <viewpoint name>* Exchange Items dialog opens. In the dialog, do the following:
   1. Select the check boxes for the <viewpoint name>* Exchanges whose <viewpoint name>* Exchange Item you want to be displayed.

   2. Clear the check boxes for the <viewpoint name>* Exchanges whose <viewpoint name>* Exchange Item you want to be hidden.

      To select all check boxes, click the Select All button. To clear all check boxes, click the Clear All button.
   3. Click OK.
      

When you hide the realized exchanges, you can choose whether you want to hide the arrow notation on the realizing elements. The Hide Information Flow If Conveyed Information Is Missing Project option controls the arrow visibility.

To change the arrow notation visibility on realizing element when the Exchange Item is hidden or unspecified

1. From the modeling tool main menu, choose Options > Project. The Project Options dialog opens.
2. In the dialog, go to General > Diagrams.
3. In the Diagrams property group, find the Hide Information Flow If Conveyed Information Is Missing option and set it to true.
4. Click OK when you are done.

Dealing with Exchanges after Reconnecting Connectors

When you need to reconnect the connector from one element to another, there are several possible options regarding the exchanges:

• None (default)
• Create New <viewpoint name>* Exchange
• Realize Compatible <viewpoint name>* Exchanges
• Update End of <viewpoint name>* Exchange
• Remove Incompatible <viewpoint name>* Exchanges

None

Choosing this option, the incompatible exchanges where source and target does not comply with new source and target, will be removed. This option is default. 

Create New <viewpoint name>* Exchange

When you reconnect the connector to a different element, a shortcut menu opens. In the shortcut menu, you can select to create a new <viewpoint name>* Exchange. The Realized <viewpoint name>* Exchange wizards opens where you can create a new Exchange to be realized instead of the previously realized exchanges.

Realize Compatible <viewpoint name>* Exchanges

When you reconnect the connector to a different element, a shortcut menu opens. In this shortcut menu, you can select to realize the exchanges, which exist between the sender and the new receiver. If the connector links ports, the conveyed items of the resulting exchanges would be ensured to adhere the flow properties on both ends of the connector.

Update End of <viewpoint name>* Exchange

Choosing this option, the end of the exchange will be updated to match the new sender or new receiver on the reconnected connector's end.

Remove Incompatible <viewpoint name>* Exchanges

Visible only when the sender and receiver are not changed after reconnection, but the exchanges that were already realized become incompatible, meaning they no longer comply with the new flow properties on both ends of the connector.
