Hello @Sapna Gupta ,
Thanks for the ask and using the Microsoft Q&A platform .
Adding to what Martin said may be the server to which you are looking is not correct . To find the correct server name , Click on the sink ->
sink datastet ->Open - > Linked service -> edit and you should be able to see server name and the database name .
Please do let me know how it goes .
Thanks
Himanshu
