Stop all the processors in your dataflow<BR />2. Start only the first processor and you will see data queue on the connection leading to the next processor.<BR />3. Right click on the connection with the queued data and select "List Queue" form the context menu that is displayed.<BR />4. You can click on the "view details' icon to far left side of any listed FlowFile from the table displayed<BR />5. From the "FlowFile" UI that is displayed you can select the "Download" or "View" buttons to get access to the content as it exists at this point in your dataflow.<BR /><BR />When you are done examining the content, repeat steps 3-5 after starting the next processor in your dataflow.&nbsp; This allows you to see how your content is changing s it progresses through your dataflow&nbsp; one processor at a time.<BR /><BR />Hope this helps you,</P><P>Matt</P> Mon, 09 Dec 2019 21:44:19 GMT MattWho 2019-12-09T21:44:19Z
