FAGL_DOCNR -document number for general ledger view- (NGL)

Hi,

I have a question about TCode FAGL_DOCNR -Define document number ranges for general ledger view-.

I want to know if this activity is mandatory when you have more than one ledger and one of them has a different fiscal year variant, or if it is also mandatory when you have two ledgers with the same fiscal year variant.

Thanks,

Cecilia
