I want to upload bulk data in ADSO through ABAP Code.

Hello,

I have data and I want to upload bulk data in ADSO cube through ABAP Code by SE38 ONLY.
So can any one please help me to provide logic for this requirement.

Note: I know we can upload the flat file data through DTP etc. But here my requirement was data needs to upload through ABAP SE38 only by batch job.

Thanks
