MEC: Change out file name dynamically

Background

Manipulating the out file name generated by the middle ware is a common scenario. By default file names are generated with a GUID (13a7a838-a706-4273-b190-9d58a79bf04e). It is more practical if the file name is human readable.

Solution

1. In the Mapper add User function to change the file name. (Note: this function should the last function in the map)
   
2. Add similar code to the function. This code set file name to the manifest information of the map.
   

   1 2 3 4 5 6

   String date = new java.text.SimpleDateFormat("yyMMdd").format(new java.util.GregorianCalendar().getTime()); String time = new java.text.SimpleDateFormat("HHmmss").format(new java.util.GregorianCalendar().getTime()); String fileName = "EDI_832_OUT_"+ date+time; setManifestInfo("map:FileName", fileName);

3. Then, configure the relevant Send (in partner agreement) object to take the given file name.
   
4. And you are done. !!!
