Re: Error message “FAGL_LEDGER_CUST023”(Define a leading ledger)

Hey Big Choi,

I think the issue is with the source than the customizing,

PSM-FM is not supported with S/4 HANA Finance and hence I think you are getting the error in Ledger

Please check the above link, slide 48 i think.

So you cant activate PSM-FM with S/4 Finance.
