Multiple issues with CDS Views and ODATA

[angeliev]

Hello guys!

I haven´t found answer to my question, so I hope someone could answer my quiestions here...

So there´s this project we have at our company where I have to deliver Data from our S4/HANA Database with CDS Views through an ODATA Services to the Frontend (SAP UI5). I managed to "write" the CDS Views but apperantly I did something "wrong" or maybe am I missing something, because I become this errors the whole time. I will attatch some screenshots to clairfy it better.

As far as I unterstood, I should be able to find this view "Z_PROF_VIEWS_CDS" in the transaction "/IWFND/MAINT_SERVICE" where I can add it. Unfortunateliy it does not appear there.

Any suggestions how can I fix this ? That would be great help.

Thank you guys in advance and wish you to have a good day! 🙂

Best Regards
Angeliev

May I ask which S/4 HANA version are you working with? I believe with > S/4 1909, you can create service definition by right clicking the CDS View -> New Service Definition.

Good morning Bygine and thank you for your answer.

I believe I have a newer version:

I tried to create a new service by right clicking on the cds views and became this as a result:

but I still can´t find it in the service explorer in:

/IWFND/MAINT_SERVICE -> add new service

Any further ideas ? 😕

Hi Angeliya,

Good Day. I don't think you need to add it in the /IWFND/MAINT_SERVICE transaction. Go ahead and create Service Binding(by right clicking Service Definition) and Publish it. And after that if you search it in /IWFND/MAINT_SERVICE you can see the Service Binding(and not service definition). But still you don't have to add it. Please refer below blog I found which explains the steps you are after. Good luck.

Hi Bygine,

thanks a lot for your help! I managed to fix this as I changed the data types of the parameters. After I changed the data types the error message disappeared and I could register the service.

The topic you have posted looks also very interesting, I would try this also to see how does it work! 🙂

Anyways, big thanks for the help, have a wonderful day! 🙂
