Tutorial Processes
Introduction to the Throw Custom Error operator
This is a very basic process that demonstrates the use of the Throw Custom Error operator. In the process, the Branch operator checks the number of rows in the input table. If there are too few a custom error is thrown.
When this process is turned into a custom operator the error appears on the custom operator in case too few rows are in the input table.
