Hi @சத்தியமூர்த்தி இரா ,
Data-driven subscriptions are available in the Enterprise edition of SQL Server, but not in the Standard edition. See more: SQL Server Reporting Services features supported by editions.
If you are doing a lot of data-driven report subscriptions, it may be worth your while to pay for that license.
If you want to implement a function similar to data-driven subscription, you could refer to the following links: Create SSRS Data Driven Subscriptions on Standard Edition.
Creating Data-Driven SSRS Reports in SQL Server Standard Edition.
Best Regards,
Joy
