Optical Archiving

Hello,

I want to save the invoice to PDF file, when the FPCOPARA is executed for corresponcdance type 0042.

EFRM is configured and the setting is to print and archive.

When the Bill Simulation is executed to print, I am using output device as ZPDF.

I was expecting to save the Invoice PDF but getting the message that Optical Archiving is not enabled.

Any clue as to how do I configure this?
