about DTP

• default It is recommended to configure the DTP with upload mode “Delta”. The deletion of the PSA data is necessary before each data load, if a “Full” DTP is used. A Full DTP extracts all Requests from the PSA regardless if the data has been already loaded or not. This means the Delta upload via a DTP from the DataSource (PSA) in the InfoCube is necessary, even if the data is loaded via a Full upload from the Source to the DataSource (PSA) by using an InfoPackage. ( which means load from PSA via DTP will load all data from PSA no matter the data were loaded before or not,so eother PSA should delted after load ,or DTP use delta even laod form Data source to PSA use delta already)
• Only get Delta Once:
• Get Data by Request: get the oldest request
• Get runtime information of a Data Transfer Process (DTP) in a Transformation : I will give detail in another blog .
• Debug a Data Transfer Process (DTP) Request:The debugging expert mode can be started from the execute tab of the DTP. The “Expert Mode” flag appears when the Processing Mode “Serially in the Dialog Process (for Debugging)” is selected.
  Choose “Simulate” to start the Debugger in expert mode.The debugging for loaded data can be executed from the DTP Monitor directly.
  Choose “Debugging”.
