Need to upload a flat file through abap program into sap bw
I have a abap requirement in BW - I need to upload a flat file data to BW system without using Application server and without storing the data in Ztables. I have to handle it thru Z pgm(ABAP).
The user will upload the flatfile from his/her desktop and also they have options to select the DSO name or Data flow name.
Our Z pgm should get these above 2 informations (File location and DSO or Data flow name) and loads the file to PSA. and then we have to load the data to DSO thru Process Chain (This also we have to taken care in our Zpgm).
I hope you understand the requirement.. Can please giude me to complete this requirement.
Thanks in advance.
