Hi Viswanath, your question is too general, please specify. What is your process? What is the issue? Do you receive an error message or a dump? Or is your question related about settings of a process?
Based on the following thread I would suggest to use V4 instead of V2: https://community.sap.com/t5/enterprise-resource-planning-q-a/odata-v2-vs-v4-web-api-comparison-limitations-recommendation/qaq-p/12736187
