Dear Sir/ Madam,

Greetings & Good Day!!!

I am user of excel 2010 and using power pivot, I developed a analytical visualization tool . Further, I altered some data in the excel file and updated it too. Again when I created this tool the the data in power pivot is different and from the ones in the graph and also I'm getting this below message " Data connections disabled" - please enable like a flash and which I'm not able to do. It would be really appreciable if you could help me on this. Many thanks in advance.

Regards,

Gabriel Martis 

Hi Fabriel,

According to your description, you are enperiencing the issue after made some midofications on yout PowerPivot data model, right?

Based on my error messaon "Data connections disabled", you can go to connection tab to verlfy if the connection is correct or not.

DATA->Connections->"Your connection"->Definition

Besides, you can try to use a trace file to troubleshoot errors in PowerPivot. Select the check box to enable creation of a trace file that logs the interactions of the PowerPivot workbook with the server and with Microsoft Excel. This trace file can help support personnel to diagnose problems.
