I would recommend sending this information to support, https://support.powerbi.com and use the "Contact Us" link.

JackNewson&nbsp;It would help if we can know what ODBC driver you are using for this query. Can you open the problematic workbook, and use the "Send a Frown" option to report this? Make sure you include the formula.&nbsp;It looks like the access violation is in the driver.

jacknewson · Answer

unfortunately the server that the Bi application on doesn't have a mail client to email is there a way of&nbsp;accessing the information required?&nbsp;the ODBC driver is sage 50 v19 &nbsp;
