Have you tried disabling AJAX for the Quotes module? To do this navigate to Admin -> System Settings -> Configure AJAX User Interface and move Quotes from the enabled to disabled panel and save.
Go to studio
in the left column with modules open tree nodes:
opportinities -> Layouts -> Sugar Dashlet -> Sugar Dashlet Listview <- press it
move num field from ‘default’ to ‘available’ or even better ‘hidden’
then press ‘Save & Deploy’
I Have got solved by the changing the variable name billing account to billing_account in line no 38 of
modules/aos_quotes/metadata/dashletviewdefs.php by firebug tool
and
i have added a line $layout_def[‘rname’]=""; in the function private function displayInputQuery($layout_def)
{
$layout_def[‘rname’]="";
$title = $layout_def[‘rname’];
}
in the following
