Hi Sahu, Hardeep - (hardeepsahu),
Thank you for reaching out to us on the Microsoft Q&A platform.
Based on the query you posted, we understand that you are experiencing difficulty expanding the pipelines and selecting the "1 Master Pipeline" within Synapse Studio.
It is important to clarify that the absence of visible pipelines when expanding the pipelines in the Integrate hub of Synapse Studio is due to the fact that no pipelines have been created on your end yet.
The pipelines mentioned in the document are intended solely for demonstrating data ingestion concepts, such as the Copy Data activity within an Execute Pipeline activity and establishing connections within a Data Flow. The document includes two data ingestion patterns with example screenshots to aid in understanding these concepts.
Should you encounter any further issues, please do not hesitate to contact us, and we will be pleased to assist you further.
