An Oracle Data Integrator (ODI) mapping keeps a target table synchronized with new data on the source. However, when a row is removed from the source, the row remains on the target.
How can the target remain synchronized with the source without truncating the target and performing a full load?
- A mapping is executed to synchronize the SOURCE_TABLE data to the TARGET_TABLE table.
- One or more records in the SOURCE_TABLE table are deleted. The corresponding TARGET_TABLE standard physical IKM does is not set to delete or truncated.
- The mapping is executed again. The deleted records on the SOURCE_TABLE still exist in the TARGET_TABLE table.
