I am struggling with the error message.

Power query is succeeded, but during the saving, "Wrapping things up", it shows 

CdsaMashupUserException

Hi @v-yanjiang-msft !

Thank you so much for quick response.

To be honest, I am so beginner that I wonder I understand the thread and follow correctly...

But I checked the "Settings/Datasets", and there was the error at "Data source credentials"!!

The server which the main table is located was no connection because of lack of user/password.

Finally, I re-enter them, the merge & save has been succeeded.

Definitely, you gave me the certain hint and lead me to the solution!

Thank you so much! 😊
