The following error is logged in web.log file after creating a new requisition and attempting to synchronize the requisition.
[Requisition-Accessor-Thread] o.o.n.p.p.RequisitionFileUtils: Trying to create snapshot for file:/C:/Program%20Files/OpenNMS/etc/imports/pending/FileName.xml, but /C:/Program%20Files/OpenNMS/etc/imports/pending/FileName.xml does not exist.
After running process mon I noticed the application performs a CreateFile operation for C:\Program Files\OpenNMS\etc\imports\FileName.xml and result in NAME NOT FOUND.
Manually copying from C:\Program Files\OpenNMS\etc\imports\pending\FileName.xml to C:\Program Files\OpenNMS\etc\imports\FileName.xml results in a successful synchronization in OpenNMS.
Running on Windows 2012 R2 64 Bit.
