When you create an error breakpoint, the Debugger pauses when the Integration Service encounters error conditions such as a transformation error or calls to the ERROR function.
You also set the number of errors to skip for each breakpoint before the Debugger pauses:
If you want the Debugger to pause at every error, set the number of errors to zero.
If you want the Debugger to pause after a specified number of errors, set the number of errors greater than zero. For example, if you set the number of errors to five, the Debugger skips five errors and pauses at every sixth error.
