Reverse Lookup / Grid

I currently have a relationship grid that works fine, but can anyone tell me how to convert this into a reverse lookup. Current Grid <Item type="MIN_DCP" action="get" select="id(item_number)"> <system condition="in">(select id from innovator.MIN_SYSTEM where program = '{id}') </system> </Item>   Reverse Relationship (not sure how set the condition) ../Solutions/PLM/scripts/ReverseItemsGrid.html 'ITName='+itemTypeName+'&itemID='+itemID+'&reverseITName=MIN_DCP&reversePropertyName=program' Thanks
