Hi Benjamin
PPOME is a workbench type of tcode. It's not at all built for easy automation. If there are even filters to get you to what you need to update, it usually doesn't work.
I would talk to your Basis team about enabling this through a standard tcode like PA30 or PP02, or through a BAPI. I have only used one GET bapi for HR data, so I'm not sure it will work, but you could look into:
BAPI_HRMASTER_SAVE_REPL_MULT or something like that.
