In the Edit Output Mapping page, you can define query result export options. Query Request Export feature must be used in conjunction with boxcarring. It allows individual queries executed in a boxcarring session request boxsession to communicate with each other. The concept is 'exporting' a specific result element so that the next calling query will get that result element as a query parameter. So, if you've two queries, namely, 'query1' and 'query2' that's executed sequentially in a boxcarring sessionrequest boxsession, and if 'query1' has a specific result element and that element is exported with the name 'foo', then 'query2' also gets a query param named 'foo'. So when this boxcarring session request boxsession is executed, the query1's exported value will be passed into query2 as an input parameter.
