We are working in Oracle 7.2.3 with rpts,report1.5 and menu5.0. We had one of payroll application program running for last five years successfully but from last one we are facing problems with that program. We are unable to run this programs through MENU. The same program if we run from outside the MENU(from OS level) it is working satisfatorily. We are getting error as a single row subquerry returns more than one row when we run the program through MENU. What could be the problem?
