We are using the above SQL statement inside a package at database server with Oracle 10g ver. 10.2. Both development and production have same version of database server. But the package failed to complie at production with error message PL/SQL: ORA-00904: "DM"."MATTER_SEQ": invalid identifier. At development it is working fine. We also tried to run only the above SQL statement at production but it didn't execute, where at development both package and only SQL statement working fine.
