Errors during transporting

Hi

I am trying to transport SNP Back up datasource form Dev to QA. There are some errors while transporting.

Error says

Field /BI0/9AATDAB will not be delivered from DataSource in source system QA

This is one of the errors.

I am new to APO please advise me if i am doing it wrong or do i have to do anything after the transporting to copy the data source.

Thanks in advance.
