Issues in mass data Upload

Hi All,

Hope you all are doing fine.

I have to do master data upload for my next project. I have gone through LSMW, DX-WB, Recording etc. and now I am quite comfortable with all of these.

As i have tested these tools for maximum 8-10 records, I am interested in hearing from you all, your experiences regarding actual data upload where volume is high and data may be difficult to verify manualy. Particularly I am interested in how to make upload faster,Error free,consistent(No record being posted twice etc.)

Your inputs would be higlhly appreciated.

Thanks a lot for patient reading.

Bye and Regards.
