Hi @Nagesh CL
Welcome to Microsoft Q&A platform and thanks for posting your question here.
Thank you for providing the screenshot of the debug options you are seeing in your pipeline. As you mentioned, you are not using any dataflow tasks in your pipeline, but you are seeing options related to dataflow debug sessions.
The reason you are seeing these options is that dataflow debug sessions are available for all pipelines in Azure Data Factory, regardless of whether they include dataflow tasks or not. The "Data flow debug session" option allows you to debug dataflow tasks in your pipeline, while the "Pipeline debug session" option allows you to debug the pipeline as a whole.
If you are not using any dataflow tasks in your pipeline, you can simply choose the "Pipeline debug session" option to debug your pipeline. This will allow you to step through the activities in your pipeline and view the data being processed at each step.
I hope this information helps you. Let me know if you have any further questions or concerns.
