Problem in Exporting Webi Report to Excel

Hi,

I have developed a WEBI report in BOBJ 4.1 SP1 on top of IDT Universe and applied Drill Down analysis.

While exporting the WEBI Report to Excel, I'm getting Images in the place of columns where there is no data.

However, images are not getting in the columns where we have data.

Please suggest as this will help me a lot.

Thanks & Regads,

Prasad.
