V15 XML Loader Access To Path Not Allowed

Question

We are just starting to test our V15 sandbox system that has just been upgraded.  We have a transaction that works fine in our older environment (V12.2) but the same transaction fails in V15. The first sequence in the transaction is an XML Loader that tries to load and XML configuration file from the local MII server where the transaction is running.  The action fails with a Access to path /directoryNameHere/fileNameHere.xml is not allowed error.
As far as we can tell, all of the filesystem/OS level permissions (Linux in our case) are the same as they are in our old environment.
Other than file/directory permissions, any ideas why this might fail?  Has anything changed in V15 that would potentially impact this?
We are not specifying a Credential Store alias (listed as optional).
Thank you,
Mike

Answer 1

At some point a 'Default File Path' parameter was added as a system property and it's value may be causing your issue.
System Properties - SAP Manufacturing Integration and Intelligence - SAP Library
Default File Path
DefaultFilePath
The path on the file system (along with the subfolders) used to store files that need to be accessed by the following workbench actions for read/write operations:
File I/O
CreateDirectory
CreateZipArchive
DeleteFile
GetFileList
WriteFile
FTPInput
FTPOutput
ADS Printing
E-Mail
Send Mail
Read Mail
LoggingXML Tracer
Web
HTMLSaver
XMLSaver
TextSaver
ImageSaver
HTMLLoader
XMLLoader
TextLoader
ImageLoader
Note
Access to the files under the previous path (and the subfolders) will be lost if the path is changed.
If the path is empty, you can access the file system, provided the file system provides read/write permissions. The same holds good for prior releases.
