@Event(ImmediateSchedulingWorkOrderSelectEvent.class)
public class BTImmediateSchedulingWorkOrderSelect
extends BusinessTask<ImmediateSchedulingWorkOrderSelectEvent>

Business task for selecting immediate scheduling work orders for processing.

This task uses a single atomic UPDATE to select and update work orders in one operation. The UPDATE filters work orders by:

• Operation center
• State = TO_BE_PROCESSED
• Processing counter < max attempts (or NULL)

The UPDATE sets:

• Processing ID
• Scheduling model ID
• State = IN_PROGRESS
• Increments processing counter (using NVL to handle NULL)

This approach prevents race conditions when multiple tasks try to process the same work orders, and is more efficient than searching first and then updating.

Returns the number of work orders selected and updated.

Since:

22.0
