Loading Data from ECC System (Standard DataSources)




§  BI Content defines 60% of BI system
§  For flat files we were creating our custom data sources
§  Data sources defined by SAP is called Standard data sources
§  Standard data sources exists in ECC system
§  We will need to get this standard data source from ECC system to our BI system
§  Once that available in BI system then we can create an InfoPackage and extract data to standard data sources

·      Non Logistics DataSources /General DataSources
§  Non-LOs DataSources name start with 0App_Area like 0FI

·      Logistics DataSources
§  LOs DataSources name start with 2lis

§  To use standard DataSources you need to activate it

Non Logistics DataSources
In Non-LO DataSources the flow is Base Table ---> InfoPackage ---> DataSource
RSA2 (Check DataSource Structure) --->RSA5 (Activation of DataSource) --->RSA6 (Post Processing) ---> RSA3 (Extract Checker) ---> Replicate Application Component (in BW system)
1)      Logon to ECC system
a)      To activate general DataSource go to RSA5
                                 i.            Expend SAP/R3, expend FI application component, expend FI-AP, FI-AP-I0 is a transactional data source
                               ii.            To check properties of the data source copy its name go to RSA2, provide name of DataSource it shows this DataSource is based on functional module
Data sources can be made by three ways:
§  Tables or View
§  Queries or InfoSets
§  Functional Module / ABAP Code, which will create an interface b/w DataSource and base table
Verify the fields if it suits your need, Data comes to standard DataSource from the tables of ECC called Base tables, Functional consultants load data to the tables of ECC. The job of BI consultant is to extract data from all these base tables to DataSource and from DataSources to the BW system
                              iii.            Select FA-AP-I0 in the RSA5 and click the Activate DataSources button from application toolbar
b)      To verify is it activated successfully go to RSA6, expend SAP-R/3, then FI, then expend FI-AP, if you find your DataSource here its mean its activated
c)       To check validity of the general DataSource go to RSA3, give DataSource name, click Extraction button, then select List button to check data

2)      Logon to BW system to get the structure of activated Non-LO DataSource
a)      In DWW go to Source System, expend SAP, double click on your ECC system
b)      Find your application component, right click Financial Accounting Vendors and select Replicate Metadata
3)      To load data from source system to our DataSource, create InfoPackage and Execute it

Logistics DataSources
In LO DataSources the flow is Base Table ---> Setup Table ---> InfoPackage ---> DataSource
RSA2 (Check DataSource Structure) --->RSA5 (Activation of DataSource) --->RSA6 (Post Processing) ---> LBWG (Empty Setup tables) ---> LBWE (LO Cockpit) ---> SBIW (Fill Setup tables) --->RSA3 (Extract Checker) ---> Replicate Application Component (in BW system)

1)      Logon to ECC System
a)      To activate LO DataSource go to RSA5
                                 i.            Expend SAP-R/3, expend MM then MM-I0, note logistics can be from MM, SD most of the times, select 2LIS_02_ITM
                               ii.            To check properties of the data source copy its name go to RSA2, provide name of DataSource
                              iii.            In the RSA5 and click the Activate DataSources button from application toolbar
b)      To verify it go to RSA3, you will get 0 records, it doesn’t mean that Base tables of ECC don’t have data, rather we need to fill the Setup tables
c)       To fill Setup tables, go to SBIW, expend Setting for Application Specific DataSources, expend Logistics, expend Managing Extract Structures, then Initialization, to make sure that there is no data in setup tables click Delete the Contents of Setup tables, it will ask for application no
                                 i.            To find application number  go to LBWE, you will find that there is 02 in front of Purchasing, it’s the application number enter it which will delete all the data from purchasing DataSources
                               ii.            In SBIW select Filling in the Setup tables then Application specific setup of statistical data click on execute in front of perform setup-purchasing, give name of run and make sure the termination date is always in future bcz data is in huge volume which takes time to load to avoid losing any records added during load time we specify termination date in future, always execute it back end, so go to Program->Execute in Background from top menu bar, enter default printer name like lp01, select immediately on next window and click save
                              iii.            To monitor this job go to SM37, once the job is complete, you can verify the records from extract checker
d)      To check validity of the LO DataSource go to RSA3, give DataSource name (2LIS_02_ITM), click Extraction button, then select List button to check data
2)      Logon to BW system to get the structure of activated LO DataSource
a.       In DWW go to Source System, expend SAP, double click on your ECC system
b.      Find your application component (MM) , and select Replicate Metadata
3)      To load data from source system to our DataSource, create InfoPackage and Execute it
a.       Right click 2LIS_02_ITM and select Create InfoPackage, provide description and click Save
b.       Update Tab
                                                   i.      Full update will load all the records without setting the marker
                                                 ii.      Initialize of Delta Process will set a marker, which indicate till this record data has been loaded
                                                iii.      Initialization with Data Transfer is used when we are loading data for the very first time and the marker was not set, it is almost similar to full update but it will also set the marker till the records are loaded
                                               iv.      Initialize without Data Transfer will just set marker so that we can use the delta load in the upcoming loads to our InfoProviders, means when in this InfoPackage is executed it won’t  load records to InfoProvider instead it will set the marker for future delta  load, select here this option
c.       Data Selection Tab
                                                   i.      To set the criteria (e.g. purchasing document, purchasing date) for InfoPackage execution i.e. from which the delta will be available, select From Value for  BUDAT (Purchasing Document Date)  like 20.04.2012, then from top menu bar select Scheduler---> Initialization Options for Source System, click Continue in pop up
d.      Schedule Tab
                                                   i.       Start Data Load Immediately and click Start button
