Web Site Punch Out Catalog Integration with SAP SRM

[Former Member]

Hi All.

I am new to SAP SRM 7.0 integration. We have developed a "eParts Store" for one of our customer. Even we have build the Catalog Punch Out functionality in our Web App. Now when client of our customer try to access eParts Store Catalog using SAP SRM PunchOut, we are able to authenticate UserName and Password. Once Authentication is done we redirect him to our eParts Catalog Page. And our issues starts here.... Nothing is get displayed in SAP SRM.

Our Web app is developed in .Net 4.5 and we have followed the OCI 4.0 norms.

Can anybody guide us on the issue?

Hi,

some things to check with the customer:

Ask for the complete call structure and check this against the specification.

what is the target in their call structure (top or parent).

When you redirect are you breaking out of an iframe? It might be that the reference back to SAP is missing. Can you check with a simple HTML page that doesn't do a redirect?

Regards,

Robin

Hi Abhijit,

you mean you can search in the catalog, transfer an item and you get a white screen in the SRM after the item transport?

Do you use NWBC or Portal?

Hi Anita.

Thanks for your time for investigating the issue.

Let me explain you in more detail:

1. We have build eParts Store web application for our client on Microsoft Platform. This is           hosted on Public IP. We have build Catalog Punchout functionality in the same application.

2. Those who want to access our Catalog, Can call the required URL with provided UserID and      Password. (http://www.xxx.com/B2B/PunchoutRequest.aspx).

3. Once UserID and Password gets authenticated, we redirect user to Catalog Page.

4. This Catalog page provide the functionality to search for parts and allow to create Shopping      Cart.

5. Created Cart then can be submitted to User's system via POST method as mentioned in OCI      4.0 documentation.

6. This works fine with our Test tool.

7. Our Clients customer have SAP SRM 7.0 and wants to access Punch out.

8. New Catalog is defined in SRM with Punchout Parameter.

9. When SRM user access the Catalog, he can see message "Please Wait, Authentication is in      progress...".

10. Users get authenticated by our system.

11. After this we redirect to Catalog page and from this point our problem start. User do not see      anything in his window.

12. When we did some debugging at our end we did not found any issue and page was correctly      redirected to Catalog Page.

About the NWBC or Portal right now i am not too sure about it. But does it make any difference? I will check and let you know.

Hope this information will be helpful to you for further analysis.

Thanks and Regards

Hi Anita.

Some more information that you asked for:

Customer is running the SAP Portal in IE browser.

Adding screen shot for your reference:

This is the screen from which they launch the Catalog.

Our Catalog App displays message for validation of User.

After successful validation user is redirected to Catalog Page where nothing is displayed in browser. Only white window.

Hi Abhijit,

maybe an httpwatch trace can help you to see what exactly happens. Eventuell you can check it in different browser modes. Does it work in Chrome or Firefox?

Hi Abhijit,

Which IE version you are using? is this IE 11 .. if yes, try to test the same functionality with IE 8 and see if this works. IE 11 gives similar issue..
