Hi Santosh,

First try to find out the dependencies and then add. It is a very tedious job.

Thanks,

Hi Santosh,

I suppose that you made your changes in a custom module with your namespace. The WCEM Dev and Ext guide gives you detailed information about the enhancement concept and provided examples.

In your case, I guess that you did not configure the 'component dependencies' correctly. In the NWDS, please check for your DC the component dependencies.

Best regards,

Hi Steffen,

I have added the  component dependencies with respect to dpu ,here we are only trying to extend a backend.crm.impl RatingReviewCRM.java  class only to edit a method called saveRating .But we are unable to do it .

we are getting the Build error as:

Check for used DCs failed: Cannot build because used component is broken: customer.com/customer/customerinteraction/bo

please guide us on this .. Appreciate  your assistance.

Hi Santosh,

HI Steffen,

Really thankful for your response on this issue feels like there is some hope to resolve this problem .

please guide us.

we checked the build.log file generated ,below is the message.

   Build failed with errors.

We get this error every time we build the application with the changes we make .

we follwed the steps mentioned  in the dev and Extn Guide chapter 9 but we still get the same error in build log.

Added to this we see there are no custom files created in this DC we are the first to try creating the custom file of the standard in this DC .

please guide us on this .. Appreciate  your assistance.

Hi Santosh,

in NWDS, please open the 'Component Browser' view and mark your custom bo module part. The 'Development Infrastructure' perspective should offer you a 'Component' view as well. Here you find the tab 'Overview'. And for 'local Build State' a link to the build log.

That log shows detailed information.

Hi Steffen,

We have opened the build log in the component view tab overview tab and local build below is the error messages captured

public class ZRatingReviewCRM extends RatingReviewCRM {

Please suggest us steffen do let us know if you need any further information. Appreciate your help.

Thanks

Hi Santosh,

ok, that's the right log now. Unfortunately, it is not easy to read as the lines are wrapped. I am sure that you forgot some dependencies. Did you create projects of all SAP standard module parts?

Your customerinteraction/bo part should have dependencies to the SAP standard customerinteraction/bo, the customerinteraction/intf and the wec/frw/tc/core.

Best regards,

Steffen

Hi Steffen,

Thank you for your reply

As you mentioned the above, While adding the dependencies we are getting the error " Some of the new references are either deprecated or protected by Access control list(ACL) "

We continue with that error and build the module but build is failed.

We defined our Custom(ZRatingReviewCRM.java) class in Backendobject-config.xml but getting

an exception while communicate with the back end: Current class [loader]=sap.com/wec~frw~tc~core~app@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@36f6a610@alive

java.lang.ClassNotFoundException: com.customer.wec.module.customerinteraction.rating.backend.impl.crm.ZRatingReviewCRM

Thanks,

Santosh

Hi Santosh,

your implementation is done in a WCEM project, right? Try to raise a CSN message that you send to SAP WCEM support. If you offer system access , you will get assistance pretty soon.
