Control empty information

Hi experts,

I would like to control delta loadings on BW. If i found empty information i generate a file with the problematic records.

I guess the logic will be as following:

LOOP at records

     Find empty records

         Append them to file

ENDLOOP

I would like then to generate the file and send it by mail to some people (but all those steps have to be automatic with an abap code)

What do you recommand me regarding your own experiences?

Thanks.

Amine
