Which table is changed during a realignment run?

The correct choice, ACDOCA, refers to the Universal Journal, which is a central table in SAP's S/4HANA Finance architecture. During a realignment run, data in the ACDOCA table is updated to reflect changes in accounting or reporting structures. Realignment runs are part of the data consistency activities that ensure financial data is accurately aligned with the current organizational structure, such as when there are changes in profit centers or cost centers.

ACDOCA contains detailed records of all financial transactions in real-time, which means any adjustments or reclassifications made during a realignment must be captured here. This table provides a comprehensive view of both general ledger and controlling data, enabling better reporting and analysis across the financial domain.

In contrast, while the other tables listed (BKPF, BSEG, and MARCO) are also important in the context of SAP Finance, they serve different purposes. BKPF is the header table for accounting documents, BSEG represents the line item details for financial transactions, and MARCO is related to controlling data, specifically around markup and costs. None of these tables is designed to be directly involved in the adjustments during a realignment process like ACDOCA.
