Drill down issue

Hi, I am also facing similar type of issue. In desktop application drill down buttons are visible. Below is the screengrab.

Here I have given below values which are present in different tables.

Now when I publish it to service this buttons are getting disappeared. As a solution of it, I tried to edit report in service, removed visualization and added back and saved. This way it retained the drill down bar. Else switching on drill down from explorer and clicking on bars. Apart from it right click on bar to drill up or down. But my client needs this drill down row.

Now when my reports are getting refreshed via gateway again all the buttons are disappearing which is frustating. Do you have any idea why is this getting disappeared?

Thanks, Nayan Rathi
