Transaction Debugging

You use this function to monitor and manipulate a transaction while it is running.

Features

During debugging, you can do the following:

Manipulate transaction breakpoints
For more information, see Breakpoint.
See the transaction's current execution state
Modify internal variables when the transaction is paused
Modify link expressions and action configurations for future executions

The system displays the actions in the following colors:

Color	Action State
Yellow	Action is being processed
White	Action has not yet run and was not skipped
Green	Action ran and the status is true
Red	Action ran and the status is false
Orange	Action ran and threw an exception
Gray	Action was not run because it was skipped
Blue	Action has an active breakpoint

If an action was run more than once due to a loop, the upper right corner displays the number of runs and the color applies to the last run. The run count limit is 9999. If an action runs more than 9999 times, the system displays ---. If this occurs, the transaction keeps running, but the count does not increment.

Activities

To run debugging for a transaction, on the SAP MII Workbench screen, choose Transaction Debug . The following tab pages appear at the bottom of the screen:

Breakpoints
Lists the breakpoints. From this list, you can create, edit, and delete expressions.
Variables
Lists all action variables through the action currently being processed. Skipped action variables are not in this list.

The value in this list is the value before the execution of the closest breakpoint. You can enter a different value during runtime to see how it affects the execution of the transaction. Link values must be changed at runtime for the new values to take affect.
Watch List
Lists the variables you want to monitor during execution. You can add and remove variables from this list.
Links
Displays the incoming and outgoing links for the action that is being processed or that has a breakpoint.
Transaction Debug
Shows the details for the execution of the transaction. A new Transaction Debug tab page appears each time you run the transaction.

When you are debugging a transaction, you can click the buttons described below to perform certain functions:

Button	Quick Info Text (Tooltip)	Function
	Terminate	Stop the execution of the transaction. Depending on the size of the transaction, it may take a few minutes to stop. When the transaction is stopped, the Terminate button is replaced with the Restartbutton.
	Restart	Restart the execution of the action in debug mode
	Pause	Temporarily stop the execution of the transaction. You can use the Continue button to resume execution.
	Continue	Resume the execution of the transaction.
	Step	Run the next action in the transaction and then pause execution.
	Create Breakpoint	Add a breakpoint at the selected action.
	Delete Breakpoint	Remove a breakpoint from the selected action.
	Delete All Breakpoints	Remove all breakpoints from the transaction.
	Close	Close the debugging toolbar and exit out of debug mode
	Export Session	Export an image (XML file) of the transaction during debugging or after execution Note The file may be large and complex. End of the note.

To edit variables, select the Variables tab in the bottom pane of the transaction screen.
