We just upgraded to 7.2.1 from 6.1.2 (WAS + Oracle + Linux setup)
Post-upgrade we were facing an issue while trying to create a new report. We are receiving the following error in the report editor.
Error:** ** No enum constant com.pega.pegarules.priv.database.sqlgen.constants.ColumnType.UNDEFINED
After upgrade; most "DB Views" did not have sufficient privileges (Such views may carry a 'red cross' icon when explored from the DB client). We recreated the concerned views using "Deployment User" credentials. The new views had the necessary privileges and the issue was resolved.
