S4HC - Financial Statement IFRS

Dear Experts,

can you indicate us which is the best practice to build a Financial Statement in S4HC according to IFRS principles?

If we create a G/L Account by nature and then we need to reclassify accounts by destination according to IFRS principles, which is the best practice to adopt?Creating different G/L accounts or using other dimensions (as Functional Areas)?

Thanks a lot

Kind Regards
