Hi All, I have one XMLP Report which is working fine. In that ex: COL_A, COL_B, COL_C and COL_D (COL_A+COL_B) is there. So today I added one more column in rtf and wrote below code for that. COL E <?(COL_A+COL_B)/COL_C?> But it's giving me the following error. Caused by: oracle.xdo.parser.v2.XPathException: Unknown expression at EOF: Any solution for this?
