Recently I come across one issue. I have a XMLP report which is giving excel output. So when I ran the report, In invoice_number column it is showing 2.01213E+12 But actually Invoice number is 2012131000014. If it is 2012131000015 also it will show as 2.01213E+12. So I tried many times with different formats and finally find below answer. In rtf for invoice tag used like this. <fo:bidi-override direction="ltr" unicode-bidi="bidi-override"> <?INVOICE_NUMBER?></fo:bidi-override> Now when I ran the report it is showing Invoice Numbers as it is.
