SAP Substitution Reasons using OVRQ

What is a Substitution Reason in SAP?

A substitution reason is a control key in SAP Sales and Distribution that governs material determination—the automatic replacement of one material with another during order entry. It answers two questions: which alternate material strategy should apply, and how the system should behave when it swaps the material. For example, it decides whether the substitution happens automatically or whether the user is shown a selection list first.

Substitution reasons make material determination flexible. The same determination master record can behave differently simply by pointing to a different substitution reason, so the business controls both the outcome and the user experience.

Substituting Reason is a process that controls, how the system performs product selection.

How Substitution Reasons Work with Material Determination

Material determination (transaction VB11) links an entered material to a substitute. The substitution reason assigned to that record controls the result. Depending on the reason, SAP can replace the material silently, offer a list of alternatives, or simply record the original entry for reference.

This separation lets one determination procedure support many behaviors: promotional swaps, discontinued-material replacements, or region-specific products, each driven by a different substitution reason.
