# After Material Production Order Change

Starts a workflow after **Materials** are assigned to or removed from a **Production Order**.

## Event Context

The event provides `Materials`, `MaterialProductionOrders`, `IncludeChildren`, `OperationContext`, `Result` to tasks in its branch. Select these values in the value editor when configuring child tasks.

??? example "After Material Production Order Change"

    Inspect the completed order associations and add operator feedback for the changed **Materials**.

## Behavior

The handler runs inside the operation's transaction. An error in the handler can cancel or roll back the operation. An After event runs after the operation boundary, while the transaction is still active.
