Hi Kittu,
I think, your requirement is to run all 3 reports and get the result of all reports and modify as per your requirement in other program and Finally save into database.
You can achieve your requirement as below
- Create a FINAL_REPORT program and call all programs by using SUBMIT or CALL TRANSACTION
- Create a class ZCL_MY_DATA and add static attributes like GT_DATA1, GT_DATA2, GT_DATA3
- In your progams you can fill the final result into global attributes
- Now, you can access the data of all internal tables in your program FINAL_REPORT
ZCL_MY_DATA=>GT_DATA1, ZCL_MY_DATA=>GT_DATA2.....
Hope this helps you.
Regards,
Rama
