Error when building APM on SAP Web IDE Full stack

[former_member516423]

Hi,

1. I've tried to do the Deep dive 12.

When I build the Java module, it generates the error.

This is CDS 2.3.2, Compiler 1.0.30, Home: node_modules/@sap/cds
Compiled 'srv/my-service.cds' to  
srv/src/main/resources/edmx/CrudService.xml

Does anyone know how to resolve it?

Hi Tri,

do you see a chance to attach the ZIP export of your MTA project from WebIDE (provided there are no sensitive data inside)?

Does this happen all the time for every for every SAP CP Business Application Project you create from scratch using the wizard?

Best,

Christoph

Hi Christoph,

I've attached the ZIP export. Please follow the link. Attachment

This happens to every Business Application project I create from scratch using the wizard this week.

Regards,

Tri

Your example MTA has a db module, which is not registered in your mta.yaml. Hence WebIDE does not know about it but CDS build still tries to access it. Please follow the last steps in the Appendix of the above mentioned blog post (https://blogs.sap.com/2018/06/05/deep-dive-9-use-the-sap-s4hana-cloud-sdk-in-the-application-programming-model-for-sap-cloud-platform/# ) and remove the db folder from your MTA project's source. Then srv will build again.

Hi christoph.pohl,

Thank you. I'm able to build and run the module alone. I've noticed some behaviours.

The $skip, $top and $orderby do not work properly.

For example:

a. https://<host>/odata/v2/CrudService/BusinessPartner?$top=1&$skip=1

The service doesn't return any data.

b. https://<host>/odata/v2/CrudService/BusinessPartner?$top=2&$skip=1

If $skip < $top like in this case, it returns only one record, not 2 records.

How can I resolve this issue because it will affect the pagination?

c. https://<host>/odata/v2/CrudService/BusinessPartner?$orderby=BusinessPartner desc

The returned data is not sorted by the criteria.

I've run these operations directly with /sap/opu/odata/sap/API_BUSINESS_PARTNER and it returns correct data.

Thanks

Tri
