Hi, I want to try and specify a SELECT_BY criteria in the Query-Tree webject (Infoengine). I understand from the documentation that this is a possible combination but I dont know how to put proper values for these parameters: <ie:param name="SELECT_BY" data="EFFECTIVITY"/> <ie:param name="SELECTBY_CONFIG_ITEM_REF" data=""/> <ie:param name="SELECTBY_UNIT" data=""/> Could someone help me out please? If possible, can I see a code snippet as example? Thanks!, Rekha
