How output parameter determination with BRFplus works in SAP S/4HANA

What output parameter determination does

In SAP S/4HANA output management, the output of a business document (for example a purchase order or a billing document) is controlled by output parameter determination. Instead of the condition technique used by classic NAST-based output control, the parameters are determined by BRFplus decision tables that are maintained per application object type.

The determination is organised in steps. Typical steps are:

• Output type — which outputs are required for the document at all;
• Receiver — who receives the output;
• Channel — for example email, print or XML;
• Printer settings and email settings;
• Form and output relevance — which form template is used and whether an output is relevant at a given point in time.

Why no output is created

When a document is saved without the expected output, the cause is usually one of these:

1. The decision table of a step has no matching row for the document's attributes (for example a new sales organisation or document type).
2. A step is missing or inactive, so the determination stops before a channel or receiver is found.
3. The form template referenced in the table does not exist in the target system or is not assigned to the output type.
4. The table content exists in the development system but was not transported consistently to test or production.

How to analyse it

• Compare the attributes of the affected document with the conditions of every determination step, in order.
• Check that the rows are active and that a fallback row exists where one is intended.
• Verify that referenced form templates, email templates and output types exist in the target system.
• Treat decision table content as transportable configuration: review which transport carries which change.

ERP Preflight's OPD Guard parses exported BRFplus/decision table content and reports missing steps, unmatched combinations and dangling references with the exact artifact location as evidence. See Output & Extensibility for the related engines.
