An accounts payable history record, which accumulates a number of important year-to-date and period-to-date amounts (such as purchases, debit and credit adjustments, gains and losses) in base currency. The history is accumulated separately across the following dimensions: branch, GL account, GL subaccount, financial period, and vendor. History records are created and updated during the document release process (see APDocumentRelease graph). Various helper projections over this DAC are used in a number of AR inquiry forms and reports, such as Vendor Summary (AP401000).
