Hello,
The file name will be however you configured it to look like within the logical file name definition. For example, if your file name is configured like this:
<SYSID><CLIENT>_<PARAM_3>_<DATE><TIME>
It would look something like:
PRD100_IDOC_201608152910
This would be a file for the archive object IDOC.
Best Regards,
Karin Tillotson
