Hello,
I found this page in the "SAP Help":
http://help.sap.com/saphelp_46c/helpdata/en/f8/096e5190fe11d293ab0000e8323492/content.htm
But, I don't have success for execute the copy assignment.
I'll go to open a ticket with the SAP Support and I return here with the their reply. If somebody has some return, please, write notification here.
Best Regards.
