OBIA 11g ETL Load failing in ODI due to java.sql.SQLException: ORA-01427: single-row subquery retur

3471971

We are running a ETL Full Load using ODI for OBIA/BIApps, against Peoplesoft database (Source). It is failing with the below error:

Is this anything to do with the Code being run against the target database or any changes to the Interface in ODI studio ? All that the Load is run is against the pre-packaged code, no customizations done yet. Running a Full Load to test the Load and view the data in BI.

ODI-1228: Task SDE_PSFT_Stage_GLSegmentDimension_LOVFilters.W_GL_SEGMENT_LOV_ID_G_Full (Integration) fails on the target ORACLE connection BIAPPS_DW.

java.sql.SQLException: ORA-01427: single-row subquery returns more than one row
