About MS Dynamics 365 Finance and Operations (AX)
The enterprise ERP that came out of Axapta.
Dynamics 365 Finance and Operations is Microsoft's enterprise-tier ERP, the lineage that started as Axapta in 1998 at Danish vendor Damgaard Data, became Microsoft Dynamics AX in 2006, and was rebuilt as Dynamics 365 for Operations in 2016. In 2020 Microsoft split the product into two apps sold separately: Dynamics 365 Finance for the general ledger, receivables, payables, budgeting and close, and Dynamics 365 Supply Chain Management for product, inventory, warehouse, planning and shopfloor. Most people in the ecosystem still say F&O or AX.
This is the tier above Business Central. Groups end up on F&O when they run many legal entities in many countries, need deep multi-currency and global tax localisation, and have manufacturing or distribution at a scale where WMS and production control matter. The data surface is wide: General Ledger and MainAccounts, CustomersV3, VendorsV2, SalesOrderHeadersV2, PurchaseOrderHeadersV2, ReleasedProductsV2, WarehouseIdentifiers and SalesInvoiceHeaders, plus the transactional tables behind them. In a warehouse, F&O becomes the group spine that the CRM, the PIM and the ecom channels line up against without a nightly export job nobody trusts.
