yes, i have posted in there as well. https://community.oracle.com/products/oracleanalytics/discussion/21479/derive-remote-directory-and-remote-file-name-from-a-lookup-or-a-specific-content-rather-typing

it shouldn't in FTP server setup as we may have different reports to send to different folders with different file name. we may use the same report with different parameters to generate a output file accordingly. so, we need to an option either type directly or an option to choose from a list.

Does bursting option works if data model is created with of procedure call ?
