How to call the Supplier Inquiry Form???

Hi All,

I am trying to call the Supplier Inquiry form with the following

 FND_FUNCTION.EXECUTE( FUNCTION_NAME  => 'AP_APXVDMVD_VIEW',
                              OPEN_FLAG    =>'Y',
                              SESSION_FLAG    =>'Y',
                            OTHER_PARAMS    => 'VENDOR_ID='||to_char(1234567))

The form does open but does not open in QUERY mode. What other parameters do I need to pass to open in Query Only mode and also query the specific vendor at the same time?

I appreciate your help.

Thanks
