There are 2 types of Task  

A) IMPORT TASK

1. It performs, inserts, update, Delete, And upsert operation
2. Max 5 Tables it operates, it Runs in 5 phase it uses
3. Apply command for its operations
4. Its operations are based on PI, But it cannot update the PI

B) Delete Task

1. It Deletes the data only one table
2. It is faster than import delete because it is global all Amp delete
3. Deletion Based on UPI Not allowed
4. Delete Task does not Require an AQuision phase, so it Runs in 4 phases
5. A Simple delete Tag is submitted to each Amp so that is Global all amp delete[Import delete does not satisfy this]
