Is it possible to start UoW transaction in application sevice and commit it in another?

[BekAllaev]

I have PaymentApplicationService where I create payment, after that I need to execute method in the OrderApplicationService which marks order for which I have made a payment as paid. I think that this should be done in boundaries of one transaction. Does ABP allows me to reach this kind of functionality?

I see that in my PaymentApplicationService I can have UnitOfWorkManager from the parent class - ApplicationService and UnitOfWorkManager have Begin method which can start transaction.

Let's say I call Begin method in procedure Foo of PaymentApplicationService. I want to commit this transaction in the Foo1 procedure of OrderApplicationService.

This is the place where I have doubts, I am not sure if the transaction that has started in Foo procedure won't be commited when Foo procedure is completed.

Are these application services called in the same request or two requests?

Because you shouldn't call another app service in a app service.

Consider use Domain Service

Hello, @maliming, thanks for response.
No I don't call one app service from another. I fire the event and in the event handler I call another app service. Are they run in one transaction? Here is the code of the first app service(take a look to the CreateAsync) - https://github.com/SergeyDavidovich/OMSBlazor/blob/dev/modules/src/StripeModule.Application/ApplicationServices/PaymentApplicationService.cs.

Here is the event handler - https://github.com/SergeyDavidovich/OMSBlazor/blob/dev/src/OMSBlazor.Application/EventHandlers/PaymentCreatedEventHandler.cs

Don't do this either. Consider calling Domain Service in your event handler.

@maliming got it, thank you for assistance. Now I see that event handling occurs in the same boundries of UoW as the code from which I fire the event.
