oDataService Request is called multiple times

[former_member706001]

We have an oDataService that receives a deep entity and with this information it creates a sales order in the SAP backend.

Now the oDataService works fine but sometimes we have a strange behavior: The oDataService is called two times of the same request. The result is, when i want to create a sales order, it creates two identical sales orders with different order id's. The creation time of the orders have a difference of 4 seconds, so it happens in a very short time period.

So my question is: When I call an oDataService once, why does it call the services two times?

I have also build security mechanism in the Fiori app and also in the SAP Backend to prevent the user to send multiple request within a minute. But it does not matter because i belive that the request is not send multiple times by the user. It seems that this happens automatically.

Any help is appreciated, thank you

It would help if you could share the code that triggers the creation request.

Please check if your service call method is calling from any other methods, and in some cases odata model refresh also calls all requests related to that service. So check your model refresh also.

Do we have any resolution for this issue , We are also facing same issue where fiori calls same odata twice and our scenarios fails all the time in our QA . It works fine in Dev system

Hi AnilTripathy, As I guess in your controller check below statement is there anywhere.

This.getView().getModel().refresh() or
This.getOwnerComponent.getModel().refresh()

These statements may not effect in Dev environment some times because of oData model versions,
in higher environments, Some cases I have observed issue with these statements.

Resolution:
Handle them with Named model refresh in controllers.
