SAP NetWeaver 7.0 BI: Data Transfer Process (DTP) / The Normal DTP …
3 Requests are transferred from a Flat File to the DataSource/ PSA and then to an InfoCube. The Data Transfer Process (DTP) should transfers all the new data from the PSA into the InfoCube via one DTP request.
Tip:
It is recommended to configured 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. Additional information can be found in the The specified item was not found..
Configuration:
- “Delta InfoPackage”
Picture 1 - “DTP definition”
Picture 2 - “Process Chain”
Picture 3 - “Dataflow”

Step by Step:
- Loading 3 Requests into the PSA via Delta upload. In this case I started 3 times the same InfoPackage. Each upload Request consists of one record. The contents of the PSA after these 3 loads looks like:

- Execute the Process Chain to load the data from the Flat File into the InfoCube. The DTP will extract the data from the Flat File (1 Request) and the existing PSA data (3 Requests) into the InfoCube. Contents of PSA after the execution of the process chain (data load):

Result: The data has been transferred to the InfoProvider and the DTP merged the Source Requests (1-4) from the PSA into one single Request. Contents of InfoCube after the data load:

The second part about the selection.
The system reads all 5 request and filters the correct record. If the records are only in 5th request, just this records are processed.
I hope this helps, Michael
Thanks for your quicker response. Now I need to know the significance of Radio Buttons: Active Table(With Archive), Active Table(Without Archive), Archive(Full Extraction Only), Change Log. Could you please explain those with DSO to DSO scenario? Ofcourse with Selections. Thank you once again..my mail id is cpsomu@yahoo.com
everyone is talking about extraction mode options (Radio Buttons: Active Table(With Archive), Active Table(Without Archive), Archive(Full Extraction Only), Change Log) but I am not able to find it at DTP. Am I missing something?
Kind regards.
I am trying to create a delta DTP for 0CUST_COMPC_ATTR data source but it throws a message that:
Cannot update DataSource 0CUST_COMPC_ATTR CL1 to a DataStore object
Message no. RSM1113
Diagnosis
You want to update DataSource 0CUST_COMPC_ATTR CL1 with delta process E in update mode to an DataStore object.
Update mode 'Construct Opening Status' is usually not permitted for updating a DataStore object. With the update modes 'Initialization of the Delta Process', and 'Delta Update', whether an update to a DataStore object update is permitted depends on the delta process,.
Procedure
Choose the full update update mode or deactivate all DataStore objects as targets for the update.
Appreciate any help..
Thanks
Vidya.
