How to debug error of "cl_wd_runtime_services=>attach_file_to_response"

[Former Member]

Hi Experts,

I use this method to open attached file. When I click on file link, an external browser is popped out with dump.

However, this dump could not be traced in ST22.

How can I debug this error?

Thank you very much.

Hi Experts,

I would like to add one point to follow up this issue. I repeat these steps:

Step1: I try to open the attachment link from SAP GUI, an external browser is opened and then dump happens in the browser.

Warning is "Service cannot be reached".

http://ldai2sq7.wdf.sap.corp:50089/sap/bc/webdynpro/sap/ags_workcenter/~wd_key005056A501F602EEB99FC7...

Step2: I open the attachment link from IE. It works as expected.

http://ldai2sq7.wdf.sap.corp:50089/sap/bc/webdynpro/sap/ags_service_delivery/~wd_key005056A501F602EE...

Step3: I go to SAP GUI and try Step1 again. It works!!!

I compare the two link, the difference is about application name and wd_key.

"ags_workcenter" VS "ags_service_delivery"

Can anyone share any ideas?

Thanks a lot.

hi Vincent ,

Service cannot be reached this error generally occurs when we have transported the code from one server to another in this what happens .....our application also is transported but say .......my code was in server1....and i have transported to server2 ...after that i tried to execute my code in server 2 it will give me an error service cannot be reached.....check out that whether a similar case might ot be there with you...to rectify just delete your web dynpro application and create a new one...it once worked for me...hopefully it will work for you also...try it

also cross check your link which you have written in thread ....is it ok?

thanks and regards,

Hi,

The link is ok.

I go to sicf and re-activate the service. Then no dumps happens. I do not know why it is not statble. After some time , dump happens again.

Hi seems to me that you are trying to access a session using a session key which is not existing or session is disconnected.

Looks to me that it is not easy as you posted here . It will be difficult for us to give suggestion with out knowing your application.

Note

Hi,

I check the service in sicf, it is activated.(sap/bc/webdynpro/sap/ags_workcenter)

Then I try open application in browser, NO dump occurs. Only if I open application in SAPGUI, this dump happens.

What should be the reason?

Thanks

[gill367]

If you are testing the application from SICF, then also are you getting the dump.

Hi,

this can be easily a browser restriction !! See in the browser setting if anything to be enabled etc.
