Issue in ALM namespace for in RQMExcelImport of TestScripts

When we are importing Test Scripts from Excel sheet, if we want to assign a new value to the Originator field of Test Script, in the cfg file we specify a command " testscript.alm:owner="Jazz User" " and to change the state, we use the command "testscript.alm:state="Draft" or <column>". But these commands used with ALM namespace dont work, whereas commands used with DC namespace like "testscript.dc:creator=<Column> " to change the Originator value of Test Case works.

Does anybody know the reason why ALM Namespace is not working.

Is there any other namespace supported or Is there any other command to change the Originator value of the Test Script.

Thanks.
