How to edit data while loading data from W/O to Standard DSO?

Hello,

I am loading data from W/O to Standard DSO, during activation it got error out due to SID failure error for one infoobject(error is due to lowercase letter).But i can't change the infoobject setting and transformation.

Is there any way to edit the data(either in W/O DSO or in new data of Standard DSO)?

Thanks and regards,

Himanshu.
