In the Statement Builder, when you create a new statement that calls a stored procedure, make sure to run the statement at least once in the Statement Builder. If you create and save a statement without running it at least once, when you attempt to configure a list box (in Proficy Portal) with the statement as its source, you will see only `return_@RETURN_VALUE' in the Available Columns list. The `return_@RETURN_VALUE' parameter is an MS SQL feature and is not a column that can be used in the list box. After running the statement in the Statement Builder, the stored procedure's resultset columns appear in the Available Columns list for the list box.
