@JGebhard I wanted to build a workflow that would do a try catch anyway. It does follow the model and would try to append sheets to an existing Excel file.
In the first instance of the outer loop a _temp.table will be written that would contain the procedures and one could follow if the loop was successfil.
Within the component an inner loop would try 10 times (you could adapt that) to finish the job. A Try Catch block would check if the operation was successful and fill a Flow Variable “success” with “y” or “n”.
A Variable Condition Loop End node will then stop the loop if the Try Catch block was successful.
The results will be stored in the _temp.table you could later check for the exact point(s) of problems and you might even use it to restart a loop for just the ones who failed.
