Hi Jo,
Have a look in Create Attribute Views - SAP HANA Developer Guide for SAP HANA Studio - SAP Library , Check step no 11 -
Select theSemanticsnode, in thePropertiespane edit theDefault Clientproperty
-->This is applicable for information model . If it is a query view, I believe if you do not project the client column, the fetched result set is client independent(need to clarify)
