Reports Access : Error message

Hi all,

I’m using a Dynamics AX 2009 version of my customer, and unfortunatly i have not access of many reports. An error message appears :

SRSReport View error id 3: Cannot find reportVend.VendorPaymentJournalTotalTrxCount.FullPage on the server under the path /Dynamics.

An other message appears for an other report : Error Reporting Services.

Can you give me the reason please ?

Thank you for your help.
