When the Debugger runs, the Designer caches the target data. You can view the cached data in the Target window while the Debugger is running or paused. You can view cached target data even if you configure the Debugger Wizard to discard target data.
You can view the following information for each row of target data:
Row number of the cached target data.
Insert, update, delete, reject, or filtered.
Column name and value.
Column name and value for each row in the cache.
If the mapping has more than one target, you can choose the target you want to display. Select a target to view from the list in the Debugger Target Display window. The targets that display in the list are the targets you selected in the Debugger Wizard. If you want to view a target that you did not select in the wizard, click Mappings > Debugger > View Target Data.
The Target window displays up to 1,000 rows. After it reaches 1,000 rows, the Designer begins overwriting data from the first row. You can clear the cache and the Debugger Target Display window by right-clicking in the Debugger Target Display window, and selecting Clear Data.
