Notification using Push Application

[Former Member]

Hello,

I implemented scenario from blog http://scn.sap.com/community/netweaver-gateway/blog/2012/12/03/gateway-pushing-notifications-made-ea...

but i can not get any push notification using HTTP Trace.

What can be a Problem?

Pull notification using "notificationstore" I see.

Hi Vladislav,

The flow of notification from backend is as follows:

IW_BEP layer --->through bgRFC ---------> IW_FND layer---->through bgRFC-------->HTTP listener

So, you can check the bgRFC monitor using the transaction SBGRFCMON at backend(IW_BEP layer) as well as gateway hub(IW_FND layer), if your notification is stuck there.

Alternatively, please also check the error logs using tcode : /IWBEP/ERROR_LOG or /IWFND/ERROR_LOG.

Also, you can check all the configuration is done as per the document:

SAP Library - SAP NetWeaver Gateway

Hi Vladislav,

Is this in error log or bgRFC monitor? And in backend or gateway hub?

Have you done both the configuration in backend as well as hub as mentioned in the links that I have provided?

Can you please tell what all configurations you did?

Best regards,

Hi Shyam,

This was the first part of the blog, where you have subscribed for a business object. The second part of the blog explains how to create a push application where you can send notification. Please check the 2nd part of the blog here:

Hi Shyam,

Use TCode SU53 to check which authorization object is missing for your user.

Hi Aakash,

What are all the authorizations object i need to assign my user can you provide me the same.

Thanks,

Hi Shyam,

The missing authorization can only be found in SU53. Please check the same. It'll be mentioned there with specific values as well.

Hi Vladislav,

Are you able to resolve the errors you were getting in ur error log.. I am getting same error in my gateway when sending data from ECC..

Regards,

Rajesh

[former_member195242 · Accepted solution]

Hi Rajesh,

The error here looks like it could not resolve the URL, i.e. delivery address. Please check your delivery address or the RFC destination that you have maintained for external server. Based on the delivery address, your external RFC destination is found where the notification will be sent.

Thanks Aakash,

I am sending data to PI server to test the notification as I cann't create external RFC to my system due security issues... I have given IP address of PI system while subscribing. I am not sure where I need to put RFC details which i create for external call (RFC type 'G')..I have posted more details in following link...

Thanks for looking into this..
