Hello Team

I have created a flat file data source and i am uploading data into Advanced DSO. in transformation, i am creating hana expert routine.when i am activiating the class generated, it says error and when i checked the inbound structure generated is not the same structure as source structure. why it is happening like this?
Further i created Advanced DSO on TOP of WDSO and created hana expert routrine in transformation, here the issue is additional field RECORD is created in inbound structure.

Because of error messages i am not able to activate the generated class and i am not able to write the code in procedure.

can you please tell me the different ways avialable to write code in procedure/method of generated class.

Thanks
Raj
