The ‘Run Flow’ task is used to run a specified flow.
If you don’t provide any further input to run flow the specified flow is simply executed. You may, however provide a new input table to run the specified flow. In this case the upper top table of the specified flow gets replaced by the new input table. Similary you may want to output the resulting output of the called flow in your calling flow. In this case, the bottom table of the executed called flow will be returned and added to the calling flow. For more complex configuration, you are able to make a manual mapping for the to-be-replaced input & output tables.
