FM based extractor
Requirement: To create a generic function module based extractor on ECC R/3 side.
a: first, we need to create the structure and function module and
b: then create the data-source.
c: Test the extractor.
Step1: Create Extract Structure in T-code Se11.
Select radio-button : data-type: enter name and press create button.
Enter the fields and description you would like to have in your data-source.
These fields you can get from standard tables from which you want to retrieve the data.
Step2: Create function module in t-code SE37.
The steps for function module are explained later in Step4.
Once we have the function module ready, we can go to Step3.
Step3: Enter details in RSO2 transaction: Application Component, function module, extract structure.
On BW side: The data-source will be visible in this application component
.
Press the field list button(F7), next to change pencil button, to set the selection parameters for the extractor.
The fields list will be coming from extractor.
Step4_01: Function module: Enter values in Tabs: Import, Tables, Exceptions as shown. Make sure the checkbox are selected.
Step 4_02: Place the code in Source code tab.
I have taken field from these tables, which are linked by a key like company code, financial transaction number or deal number.
Tables: VTBFHA,VTB_ASGN_LIMIT,VTB_ASGN_POS,VTB_ASGN_RELAT,VTBFINKO.
I have attached the code later.
Step5: Test in RSA3. Give the extractor name and press enter.
We have got 21 records as our output.
Step6: Code Structure:
Steps
Part A
**1 - Tables and Internal tables declaration
Part B
**2 - Declare Output internal tables similar to Extract Structure
**3 - Declare selection screen and other counters
**4 - Capture Select ranges values
**5 - Capture Extractor
* Check DataSource validity
* Fill parameter buffer ranges for data extraction calls
Part C
**6 - Use Open Cursor for first and main select statement
**7 - Other Select Statements
**8 - Generate Output data
**9 Assign the final output internal table to E_T_DATA for result set

Step7: BW-side: Replicate the data-sources for the ECC Source system.
You will find your newly created data-source in the list of application
component.We know the application component we have chosen is TR-CM.
Create info-package and you can do the first load till PSA.
