Hi sarkar
yes you have to write an ABAP code to fill the data in the newly added field in the extract structure.
1)Go to RSA6 and find the data source you need to enhance.--> Display
2)Double click on the Extract structure.
3)Now click on the append structure button to add the required field on to the existing structure.
4) add your required fields with ZZ appended to your field.
5) Save & Activate the append structure. Then go back and make sure you activate the extract structure also.
6) Now again go back to RSA6 and select your Data Source. But this time go to change Data Source to remove the hide option to the enhanced fields. By default they’ll be in hide mode. If you don’t remove the hide field then this field will not be seen in BW side.
7) Now go to SE38 to write the logic to populate the data into the enhanced field. Program name to write the logic is ZXRSAU01.
8) Check + Save + Activate.
9) Check in RSA3 if data is populated as per your requirement.
10) Replicate your Data Source.
11) Now go to Data Source/ Trans. Structure screen. Now you can see the enhanced field on the right hand side.
Go to CMOD.
1. To  Save give Description  createcreate new project—give the project name
2. Select the radio button Enhancement Assignment and give the Enhancement name you want and press Enter.
3. If the Enhancement is already assigned to some other project it will display the same message saying it is already assigned it some other project.
Click on4. If the Enhancement is not assigned to any project save.
5. Give RSR00001 (For Variable Exits)
6. Activate the Project.
7.  and click on the components button.Now go to Display
8. Now Double click on EXIT_SAPLRRS0_001. In that you can see an include ZXRSRU01.
9. Double click on that include, it will say program name ZX…… are reserved for includes of exit Functions groups.
10. Just Press Enter.
11. It’ll Pop-Up a window  Create Object.saying Include ZX…. Does not exits
modify according to your requirements.
Hope it will help u.
Thanks & Regards
