In the SAP MDG rule-based workflow (RBWF), the process logic is defined within BRFplus decision tables, primarily the "Single Value Decision Table" (e.g., DTSINGLEVAL). This table uses the current change request status and the previously executed workflow step as inputs (conditions). Based on these inputs, the table's result columns directly determine the subsequent flow. These result columns explicitly define the next workflow step (NEXTSTEP), the next change request status (NEWCRSTATUS), and the possible actions available in the user interface (UIACTION).

A. Predecessor steps in the workflow: The logic uses the immediate predecessor step as an input condition but does not determine the historical path or all possible preceding steps.

E. User responsible for the next workflow step: This is determined by a separate "User Agent Decision Table" (e.g., DTUSERAGTGRP...), not the primary process logic table.

1. SAP Help Portal, SAP S/4HANA 1909, "Configuration of the Rule-Based Workflow": This official documentation details the decision tables used in the RBWF. It specifies that the "Single Value Decision Table" (DTSINGLEVAL) contains the result columns Next Workflow Step, New Chg. Req. Status, and Cond. UI Action, which directly correspond to the correct answers. It also describes the separate "User Agent Decision Table" for determining the processor.

2. SAP Help Portal, SAP S/4HANA 1909, "Service Level and Process Flow": This document explains the process flow control in MDG. It states, "The rule-based workflow enables you to define the process flow of a change request based on the change request attributes... The result of such a check is the next step in the process and the status of the change request." This supports the determination of the next step and status.
