Hi Clinton,
I got solution for this issue.
If you get the same issue what I had ("Unknown Exception RDR::GET NEXT"), then please try my tips.
Basically when you go for VIEW DATA for any of ODP Extractors then BODS system will read all this data and viewing based on our selections if you specify. some times BODS system will not read all the data due to huge amount data in source tables. In this case, just load the data in one temporary table in BODS system and execute the job. Then load data to target from the temporary table.
Might be this will work. please let me know if you need any clarifications.
Thanks,
Chinna.
