Hi, Not sure what is the problem with the current situation. Usually when the first process group finishes and send the flowfile to the second process group, this flowfile will be dropped when executing the the "GenerateTableFetch" in the second group and new flowfiles will be generated based on that. Another option if you dont want to have any relationships between the first and second process groups through output\input ports and make them completely independent where no flowfiles are transferred between them is to use the Nifi Rest Api to trigger the second group GenerateTableFetch from the first group using the InvokeHttp Processor. Hope that helps. Thanks
