    Hi Jyoti deka,

    Bulk loading option will not work for delta load. Use it when you are truncating and loading bulk data.

    use Auto correct load and allow merge in target table options, it will be dead slower if your source and target are not in same database.

    You can use table comparison or outer joins to perform Delta load.

    You may untick Delete before loading option in the target table. The previous records will remain in the Target table. and the NEW source data will be appended in the target table.

    Or you may create 2 conditional WF one for 1st load and 1 for delta. they will have both same target table the only difference is DELTA load will have 2 sources, the TARGET TABLE itself and the Delta Source. Join these tables to get only NEW DATA or Newly existing data to be appended in the ORIGINAL target table. Please take note that delete before loading unticked.

    • to avoid the duplicates you may use SELECT DISTINCT.. or LEFT OUTER JOIN the TARGET TABLE and NEW SOURCE and get only the NEW RECORDS in the source. Just use key field/s for this. if the key field/s is/are not available in the TARGET then this is a new RECORD in the SOURCE.
