OpenText Data Archiving for SAP Solutions and SAP Archiving & Document Access 10.0 by OPENTEXT ????
Open Text Data Archiving for SAP solutions refers to SAP data archiving mechanism
SAP Archiving & Document Access 10.0 refers to Document management scenarios using Open Text.
Both are 2 different solutions but both of them use Archive server in the backend to store data.
Hope this helps.
