# Before Entity Save

Starts a workflow before a **Material**, **Container**, or **Resource** is saved.

## Event Context

The event provides `Entity`, `EntityType`, `PersistedEntity`, `OperationContext` to tasks in its branch. Select these values in the value editor when configuring child tasks.

??? example "Before Entity Save"

    Inspect a **Material**, **Container**, or **Resource** about to be saved; reject an invalid pending value with Throw error.

## 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.
