How to set Event-Based IntegrationSubscriptions for Action.

Iam trying to generate ProductionOrder_OB report through Event-Based IntegrationSubscriptions. I have added the SysIdOutboundInterfaceWriteRequest in order to generate the outbound data. here is my code below

 public void sendOutboundInterfaceWriteRequest(ActionBasedWorkflowContext<ProductionOrder> context) {

    for (ProductionOrder ProdOrder : context.getCurrent().getModels()) {
      ModelDataService modelDataService = Services.get(ModelDataService.class);
      ProductionOrder currentProductionOrder =
        modelDataService.readById(ProductionOrder.class, ProdOrder.getSysId(), context.getPlatformUserContext());

      OutboundMessageService outboundService = Services.get(OutboundMessageService.class);
      
      QueueRef queueRef =
        QueueRefImpl.create(context.getPlatformUserContext().getValueChainId(), null, "Outbox/EXPORT_PRODUCTION_ORDER");

      SysIdOutboundInterfaceWriteRequest sysIdOutboundInterfaceWriteRequest =
        new SysIdOutboundInterfaceWriteRequest(
          "MFG.ProductionOrder_OB",
          "2.0",
          queueRef,
          ListUtil.create(currentProductionOrder.getSysId()),
          null);
      try {
        outboundService.writeSysIdBasedOutbound(sysIdOutboundInterfaceWriteRequest, context.getPlatformUserContext());

      }

      catch (Exception e) {
        LOG.error("Failed to send Production Order", e);
      }
    }
  }

Here is my ProductionOrder_OB

I have also set up PLT.MessageRoute_IB.csv, PLT.MessageQue_IB.csv and pLT.MessageDestination_IB.csv. So here, Iam getting OB report even I disable subscription.
