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. !!!

Development with MEC older version

Presently I’m working with a MEC older version (Ver 9.1).

This version is not part of an Eclipse plugin. It’s a standalone application that use for MEC mapper development. Very tedious to work with.

MEC Mapper different than the Eclipse version. But Flat file definition tool, it’s manager & the partner agreement tool looks the same.

Mapping manger looks like this.

1. Load button to retrieve all the existing mappings.
2. New button to create a new one
3. Generate & Publish buttons to compile the map & deploy to the server
4. Import & export button: Once you create a map, you cannot change it. Instead, import existing version and export with a new changes and new version number

Mapper looks like this.

1. Mapping flow is organized in “tree-view” like structure.
2. You can generate the map from this screen. But to publish you have to close this and go back to Mapping manger & publish.
3. Two options to save (to DB & to File)
4. Validate map option also available on this screen.
