How to interview feedback report in OTBI Pivot table

Summary:

Hi All,

I have developed an OTBI report on Interview Feedback. It works fine if I run for only one req and one candidate. But if I run for the whole req it gives unwanted empty columns. I want to remove the empty columns.

Please help fix this issue.

Yours truly,

Robinson Ng
