Hi,

main_program: Sort key "START_DATE" no longer exists in dataset schema. It
will be dropped from the inserted sortmerge collector.
main_program: Sort key "REASON_CODE" no longer exists in dataset schema. It
will be dropped from the inserted sortmerge collector.
main_program: There are no sort keys in the dataset schema. No sortmerge
collector will be inserted.]

Hi,

Check this Fields START_DATE & REASON_CODE from reading dataset. It seems it is not available from source dataset.
