You can create an export process to output information about records in the results of a query. You can build an export process using a selection of query results and an export definition, the selection will determine which records are in the output and the export definition will determine what information will be output for each record into a spreadsheet. However, you may notice when building the export process that you cannot find the correct selection for the ad-hoc query you want to use.
Make sure that you have created a selection for the ad-hoc query you would like to use. Any time you want to use the results from a query in another area of Altru, for instance in a mailing or in an export, you must create a selection from the results.
Go to Analysis>Query
Highlight the desired query in the list and click Edit
