[anubhavpandey]

In previous few blogs, we saw how the structure of an OData service, service document, metadata, URI convention and also created an OData service from scratch.

[sasibhushan_kumar]

Good work Anubhav.. I appreciate your efforts for preparing this sessions.

[anubhavpandey]

Hi Anubhav, Appreciate your efforts, it's good learning. Would you share some demos on these topics. 1. Association and Navigation. 2. How to navigate to Items from Header. 3. Assuming there are 1000K records how do you improve performance without loading all the records. 4. Expand query option. 5. Any complex business scenarios which might be useful in the project.

[anubhavpandey]

Thanks Ram.

I certainly intend to author more blogs on OData advanced topics however, this blog series was intended to cover the basics.

to answer your question on performance, there are many techniques which are available such as implementing $expand, soft state, $top and $skip for paging, $select to pull only the required data from backend as so on.

You can refer to the following blog authored by one of my colleagues on performance topic that might help you.

Hi Anubhav!

May I ask some additional questions?

1. can you please share your PPT/PDF slides you have shown in the youtube videos?
2. will you also continue this blog covering the SAPUI5 SFLIGHT Part?
3. can you please share the ABAP code? There have been some exceptions if have never seen and although you said your ABAP was straight I think it was bright enough!
4. it did not quite understand what was the difference of entity and entityset in Flightcarrierset.
Concerning your ABAP code I think that flightcarrier_get_entity is just for ONE special carrier as  inputparameter and flightcarrier_get_entityset is select *.
When connecting it to the Serviceimplementation: I think getEntity (Read) is for flightcarrier_get_entity and getEntityset (Query) is for flightcarrier_get_entityset.

I do not get quite the difference when do I use (Read) and when to use the (Query) service?

Big thank you for that useful course.

[former_member514516]

Very useful course so a big thank you for that! Hope you can create one for the SAPUI5 app that consumes the OData service.

[anubhavpandey]

I have not been able to write further blogs on SAPUI5 developments. Will keep that in mind to provide an end-to-end experience.

Thanks!

Hi Anubhav,

 

Thanks for writing this blog.

I have created a sample OData service. All the steps are performed as mentioned in this tutorial.

But while registering service, have not got any server(GATEWAYLOCAL) under Service Maintenance in TCode SEGW.

Can you please guide on the step that might be missed.

 

 

Regards,

Pranav
