SAP Business Warehouse Question:

DTP is new in BI 7,

In BW infopackage brings the data from Source Sytem to PSA
& InfoCube(Data Targer).

But from BI7 Infopackage brings data upto PSA. first u need
to create transformation either from

PSA(Data Source)--InfoCube or
InfoCube to PSA(Data Source) when u create transformation
then u can see the field mapping between souce fields to
target fields. Also u have conversion rules etc...

Now u can create DTP two ways...

PSA(Data Source)--InfoCube or
InfoCube to PSA(Data Source)

In Dtp u have 3 sub tabs,
1. Extract Full, Delta (only Change or new data)
2. Update
3. Execute--- Execute button.

After Executing u can go to monitor...
