Because UC's authoritative Orders and Contracts exist in SAP rather than Salesforce, the appropriate Sales Agreement actuals configuration is Manually using API upload. This mode supports scenarios where actual quantities and revenue originate outside Salesforce and must be supplied to Manufacturing Cloud through an integration.

Salesforce's current Sales Agreement actuals architecture explicitly uses Manually via API Upload for scenarios in which actual information is loaded and then processed. Salesforce's DPE-based actuals workflow also identifies this mode as an applicable configuration for externally supplied order information.

The other two modes rely on Salesforce Order relationships. Automatically from direct orders calculates actuals from qualifying Salesforce Order records associated directly with a Sales Agreement. Automatically from orders through contracts derives actuals from Salesforce Orders associated through Contracts. Those modes are appropriate only when the relevant transactional records and relationships are represented inside Salesforce.

For this manufacturer, SAP remains responsible for operational order and contract processing. The integration should therefore transfer the required actual information into Salesforce through the API-based process while preserving SAP as the operational source.
