One of the important applications of openFT products is to transfer a file to a target system with automatic follow-up processing of the received file. In many cases, the receive file is actually only an intermediate product of the processing involved. In order to prevent potential conflicts with concurrently running requests in such cases, the metacharacter string %UNIQUE or %unique can be specified in the receive file name as to instruct openFT to create a unique file name. openFT replaces %UNIQUE or %unique with a string which varies with each new call. The string length depends on the platform.
Note that in log records, result logs, the status output of transfer requests, and in messages, the file name is displayed using the values that have already been set for %UNIQUE.
