Posting to statistical project and commitment values from purchase order are two types of postings that update the ACDOCA universal journal table. The ACDOCA universal journal table is a table that stores all financial accounting and controlling data in SAP S/4HANA Cloud in a single structure. It contains various fields for different dimensions, such as general ledger accounts, cost elements, profit centers, functional areas, or segments. Posting to statistical project updates the ACDOCA table with statistical values that are used for reporting purposes only and do not affect any financial statements. Commitment values from purchase order update the ACDOCA table with commitment values that represent future obligations or liabilities based on purchase orders or contracts.
