Hello All ,

Need your assistance on error message in Enterprise portal (QA)"No content available for this navigation node", What i have observed that this message is appearing only for one BW report after the report modification and recently portal upgrade to 7.5 .

The issue is only in EPQ , report appear to be correct in BI (Dev , QA and Prod ) as well as in EP (Dev and Prod) only issue in EP QA .
