I configured my safe pay file format, exported it,, imported it, creating the upload maintenance file and then ran the transactions upload. The format appears as it should be in the configurator, however, the exported file is not the same format. Why is it changing from the export to the actual file?
The file that is created during the Safe Pay format is set on the Configurator.
I would first double check that and make sure that is correct.
You state that you configured, exported and imported. What was the reasoning behind Exporting and importing it? Did it go to a different environment? Perhaps the configurator got corrupted during this process. What happens if you recreate it in the environment, it is in? Should only take 5 to 10 min to recreate it if you have one already.
One other thing I would check is to see what your Default File Types in windows. In window, search for Choose a default file type for apps. Locate the file type and verify it is set correctly. Example of text is below.
