Let me know the BIW 7.0 flow

Question

Dear All,
I am new to this BIW 7.0, before i was working with 3.0B. Kindly let me know the difference between this two. I could see here in the Modelling area Data Sources, DTP, Transformations and so many areas here. Let me know this flow in detail. Kindly help me in this regard.

Sathiya

Answer 1

Hi Sathiya,
1.     I want to know the difference between the transformation field in the data source and transformation field in the data target also.
[Anil]: Qn is not that clear, but just in case if you want to know about transformations then below are the links.
Transformations

Difference in Transfer/Update rules routines to Transformations of nw2004s

2.     Why there is a field in transfer rule in data source tree?
[Anil]: If you are in BI 7.0 you don’t need transfer rule. You can map the fields in the data source to the data target with transformations. Right click the data target and choose transformations and give the data source name and you will be guided.
3.     What is migrate in the data source tree?
[Anil]: Below are few important points:
•If you want to migrate your 3.x DataSource into a SAP NW 2004s BI DataSource, then use the inbound adapter functionality – which will mean losing your DataSource, Transfer Rules and PSA. Bear this in mind if there is complicated logic within your transfer rules. You will need to migrate this earlier into a transformation. Then you can do the DataSource migration. This will mean a new PSA table will be generated. There should not be data in your PSA table when you do the migration, as it will be lost.
•You do not have to migrate all your update/transfer rules to the new concept. You could still define update/transfer rules in SAP NW 2004s, although this is a little more hidden – available via Additional Functions in context menu.
4.     What is data transfer process in data source tree?
[Anil]: Here is the Step by step process to create DTP -

5.     How to load master data is this same like 3.0b??
[Anil]: No, it is not the same. But for loading hierarchy we still follow the 3.x procedure. Below are the steps for loading master data:
1. Create the infoobjects you might need in BI
2. Create your target infoprovider-Infoobject
3 Create a source system
4. Create a datasource or use replicated R/3 datasource
5. Create and configure an Infopackage that will bring your records to the PSA
6. Create a transformation from the datasource to the Infoprovider
7. Create a Data Transfer Process (DTP) from the datasource to the Infoprovider
8. Schedule the infopackage
9. Once successful, run the DTP to get data from PSA to Infoobject
10. Check Infoobject for data
loading Infoobject using Flat-File

6.     If we are taking from more than one data source then how we have to process?
       [Anil]: Below are different scenarios in using data source.

Assign points if this helps.
