Error while transfer SC back to SRM using a direct NWBC-URL

[Former Member]

Hello,

we are using SRM7 with NWBC and I created a URL to get directly to the the shopping cart:

http://xxx.xxx.com:8001/sap/bc/nwbc/~canvas/wda/sapsrm/wda_l_fpm_gaf/?WDCONFIGURATIONID=%2fSAPSRM%2f...

That works fine. But when I jump to our 3rd party catalog provider and transfer the shopping cart back, I get an error without any further information, just "An error has occurred". This URL was called:

http://xxx.xxx.com:8001/sap/bc/nwbc/?sap-nwbc-has_post_params=X&sap-client=001&sap-language=EN&sap-n...

When I use the link http://xxx.xxx.com:8001/sap/bc/nwbc/srm/ I have to do one click more ('Shop'), but it works.

Has anybody an idea?

Thanks and regards

Hi Johannes,

I'm sorry to bother you but I was wondering whether you have been able to solve the issue.

From my point of view SAP seems to have programmed SRM in a way that we can't call the webdynpro shopping cart application directly and then use it to import catalog data.

We ran in to the same issue today and found you post. Have you been able to the issue?

Thank you for any inputs and responses. If we manage to find out how we resolved this we'll share it here as well.

Kind regards,

Hello Tim,

I could not solve this issue. I was in contact with SAP. The current design does not allow that, using an external catalogue. Now we go the mainpage and are using the standard "way". This is one click more than a direct link.

If you find another solution, please let me know.

Hi Johannes,

could you please show, how have you defined SC-App in the role.

I'll try to reproduce it in our system.

Hi Johannes,

yes, what do you have in PFCG for your shopping cart application?

I'll try to reproduce it in our system.

Hello,

should be the same as you have:

Hi Johannes,

how do you jump to catalog? From sholling cart or directly from NWBC?

Hello Konstantin,

I jump from Shopping Cart (standard). Just the link to the shopping cart is created manually.

Here you find the config of the external webservice:

Hi Johannes,

my suggestion is:

1. Install firefox with addon firebug

2. switch on firebug for all sites

3. check HOOK_URL transferred by the catalog call and compare it with the called by catalog URL by transferring items back to SC.

Hello Konstantin,

yes the hook-url is different. See below.

Any idea how to solve this problem?

Thanks and regards

Hi Johannes,

as I understood, sent to catalog HOOK_URL is changed, and catalog calls wrong URL back.

Yould you please compare it with standard SAP role. Will it work? Do HOOK_URL's the same?

Hi,

in my post above you find this comparism.

For example the sap-nwbc-action_url is empty when I call the shopping cart directly.

Hi Johannes,

have you checked following notes?

Hello Konstantin,

unfortunately the notes do not solve my problem.

[konstantin_anikeev]

Hi Johannes,

please try following for both cases.

Set a break-point in

/SAPSRM/CL_CH_WD_NAVI_SERV->/SAPSRM/IF_CH_WD_NAVI_SERV~LAUNCH_CATALOG

and check the difference in generation of HOOK_URL.

In Standard SC app is started in separate window. How does it work for You?

Regards

Konstantin

[Former Member]

Hi,

the hook-url generated in this class is equal in both scenarios. I took a look at the outbound handler. Here the http-request reads with a system call the parameters. Here it is different. So I think the difference is somewhere between the call of the class you mentioned and the call of the outbound handler.

Regards

Johannes
