Re: In SAP ECC 6.0 can we copy master data from Production to Development

Hello

A copy from production to development is not a usual practice.

I suggest you to read this SAP note first.

Note 130906 - How can versions be transported?

Regarding the copy profiles

If you still need to perform a copy of the production data to the development system then the best option would be system copy (backup and restore) instead of a client copy.
