I don’t think it’s D or C. Option A is what matches S/4HANA behavior, since margin analysis updates COGS at delivery using Universal Journal integration. Costing-based (C) is a bit of a trap here, because it usually posts COGS at billing in classic setups, not at delivery. Pretty sure that’s the intent unless they mention custom configs. If anyone's found otherwise on live exams, let me know!
I don't think C is right here. Margin analysis (A) is the only one where COGS gets posted at the exact time of delivery, not at billing. Costing-based typically updates at billing, which is a trap in the options. I'm pretty sure it's A unless SAP changed something really recent. Disagree?
