Replicat Abending from OGG12C->OGG 19C (source and target DBs are 12c): OGG-01296 Error mapping
I have an oracle 12C table (both source and target) getting replicated from OGG12C to OGG19C, which has unique index defined on 4 columns. No PK and none of the columns are "NOT NULL" in the unique index. OGG12C-->OGG12C works fine however replicat is abending with OGG-01296 Error mapping if OGG source is 12C and target is 19C. I added a "NOT NULL" constraint to one of the column which is part of Unique Index and replicat started working fine. Is it a bug or expected behavior?
