Paloma has heard from the accountants that they report on levels bellow the company code using segments. She has checked in the system and sees that segments are already maintained, but does a deep dive to find out more about them and their role in financial business transactions and reporting.
Segment reporting breaks down the operations of a company into manageable pieces, or segments, to satisfy US GAAP and IFRS reporting standards. You can define segments in customizing in SAP S/4HANA.
Annual financial statements supplemented by the segment information from segment reporting provide deeper insights into the financial position, asset position, and profit situation of a company.
