Check that the FDM Service account has full read\write Share and NTFS permissions to the application folder directory:
a) Choose <Add Application> at the login form and login
b) Highlight the application in the list and choose "Modify"
c) The Application path will be displayed.
Make sure that the UNC Path is valid, that the you can reach it, and that the Application Folder Name matches the name of the application.
Thank you very much for all of your reply. This issue has bee resolved earlier and I just want to share what we have done and close this post.
Per my IT team, the FDM task manager wasn't set up correctly for the batch loader to run. Therefore,
1. we needed to set up the FDM task manager again;
For the file name, as we would like to use the custom description for the Period (e.g Q1 - 2012), therefore
2. we needed to turn on the "Allows custom description in period." setting (in Admin --> Configuration); and
3. put spaces between Q1 - 2012 in the file name for batch loading (e.g. we cannot put <version>_<location>_<category>_Q1-2012_<RR>.txt, needs to be <version>_<location>_<category>_Q1 - 2012_<RR>.txt)
The batch loader is now working properly.
