HOW DO YOU PARFORM INCREMENTAL LAOD ?..

Answer / sagar chowdary

By using the date column in the source we do incremental load,
specifying the start date in source qualifier,changing the
start date in parameter file in future.
With this in mind, I will expect a load pattern like this

Every extract from the source will be a full load
Every load in terms of records, will be equal to last load + new records – deleted records
80-90 % of the extracted records will already exist in the valid table instance
Every load will be incrementally larger than the previous load, as more records are added to the sourceThinking
