Questions:
What are the key benefits of using a DTP over Conventional IP loading?
Refer to section Key Benefits of using a DTP over conventional IP loading.
What are the different types of DTPs?
It seems like there is only one Standard Type of DTP. DTPs can use different DataSources as shown
in section DTP can use the following as DataSources.
How to create Data Transfer Process for different types of DataSources?
What is the t-code to create a DataTransferProcess?
Start in RSA1 - Modeling - DW Workbench.
What does Only Retrieve last Request option under Full Extraction Mode on Extraction tab do?
What is Temporary Storage Area in Data Transfer Process?
What is Erro Stack in Data Transfer Process? How to look at Error Stack? How to delete Error
Stack?
How to use Semantic Keys in Data Transfer Process?
DTP is the Transfer of Data between two persistent objects. SAP Net Weaver 7.3, Info Package
loads data from a Source System only up to PSA. It is DTP that determines the further loading of
data thereafter.
Data Transfer Process is used to:
Data Loading from PSA (Persistant Storage Area) to InfoProvider(s).
Data Transfer betweeen Info Providers within BI.
Data Distribution to targets outside BI, e.g. Open HUBs, etc.
Key Benefits of using a DTP over conventional IP loading DTP follows one to one mechanism between a source and a Target i.e. one DTP sources data to only
one data target whereas, IP loads data to all data targets at once. This is one of the major advantages
over the Info Package method as it helps in achieving a lot of other benefits.
Isolation of Data loading from Source to BI system (PSA) and within BI system. This helps in
scheduling data loads to Info Provider at any time after loading data from the source.
Better Error handling mechanism with the use of Temporary storage area, Semantic Keys and Error
Stack.
is the ICON for DataTransferProcess Objects.
Creating DTPs: Right click on the DataSource and choose Create Data Transfer Process.
DTP Type:
Object Type for Target of DTP:
Subtype of Object:
DTP can use the following as DataSources:
Data Transfer Process (DTP) contains three tabs: Extraction, Update and Execute.
EXTRACTION Tab:
1. Parallel Extraction new option in BI 7.3 – could not find this option.
2. Delta Init. Extraction from – could not find this option.
Two Extraction Modes:
More options with Delta Extraction Mode:
Delta Init without Data is a new option in BI 7.3.
Filter option can be used to filter data based on conditions:
Semantic Group
UPDATE TAB
Maximum Number of Errors per Pack – after which the load process terminates.
Error Handling options:
1. DTP Settings to Increase the Loading Performance
2. Handle Duplicate Records Key
EXECUTE TAB
1. Automatically Repeat Red Request in Process Chain new option in BI 7.3)
Data Transfer Process (DTP) BI 7.3
Data Transfer Process (DTP) contains three tabs
1. Extraction
2. Update
3. Execute
Detail Explanation Each Tab
1. Extraction
There are two types of Extraction modes for a DTP – FULL and DELTA.
When the source of data is any one from the below Info Provider, FULL and DELTA Extraction
Mode is available.
Data Store
Info Cube
Multi Provider
Info Set
Info object :Attribute
Info object :Text
Info object :Hierarchies
Info object :Hierarchies (One segment)
Semantically partitioned objects
Info object :Attribute
Note: Now in SAP BW 7.3, we can extract data from Multi Provider and Info set which is not
possible in earlier version BI 7.0 and BW 3.5
Please check the below screen.
In the process of transferring data within BI, the Transformations define mapping and logic of data
updating to the data targets whereas, the Extraction mode and Update mode are determined using a
DTP. DTP is used to load data within BI system only.
If you selected transfer mode Delta, you can define further parameters:
A. Only get delta once:
It can select this option where the most recent data required in data target. In case delete
overlapping request from data target have to select this option and use delete overlapping request
process type in process chain. If used these setting then from the second loads
