No Edit Button when open object page via custom action (Button) RAP, BTP, ABAP Environment

[sebastian_wilhelm1]

Hi Experts!

I created a custom action with abstract entity (Button: open Product opening a popup) to select and display an entity on an object page.

I implemented a method for the action with some dummy-data.

I tried somethind like %action-edit but the the variable %action is not availabe there.

I can display the object page but the fields are not editable.

Any ideas how I can make the object page editable?

Thanks,

Sebastian

Is the object page editable when you press the Create button?

Is the standard operation

update;

enabled in your behavior definition ?

And are you using

use update;

in the behavior definition in your projection layer?

[sebastian_wilhelm1]

Yes, yes and yes.

The object page is editable when I press the create button.

I created a Definition in Root View and propagated it to the upper levels

Any luck?

Hey Sebastian, what did you do to make it work in managed scenario?

[Andre_Fischer]

You can use the following syntax in the BDEF or your R-view

internal create;
update;
delete;

and in the BDEF of your projection or interface view you would have to comment out the use create; statement.

// use create;
use update;
use delete;

Hi Andre!

I tried the coding for managed, unmanaged and custom entity (also unmanaged). Clicking on the custom "createRun" button in the unmanaged scenarios, the object page is still not editable (my initial problem). Clicking on the button in the managed scenario, the page is shown in "edit mode" (with a edit and a save button). But as described above, there must no create or save button.

Is it possible to display an editable object page without a save or create button? There are scenarios, where you don't want to create or save something. Just processing some data. I'm thankful for any information. I'm struggeling whith this since weeks.

Hi Sebastian,

thank you very much for the nice feedback about my generator :-).

The scenario that you describe sounds like it could be tackeld by using a custom entity.

The custom entity could be used to retrieve the data from the connected on-prem system. (So I assume you are building the app in a Steampunk system ?).

A custom entity could also have the option to deliver some sample data.

How to implement a custom entity in the ABAP RESTful Programming Model using remote function modules...

In the above mentioned blog I used a demo mode in case no real backend is connected.

My generator would also be able to generate a RAP BO based on custom entities provided you define the datasource as an abstract entity.

A second option could be that you use so called virtual elements in your entity. The data for these virutal fields are also calculated by an ABAP class.

Kind regards,

Andre

Hi Andre!

Thanks for the example. I already tried the approach with a custom entity, but the problem stays the same - the display of the create button.

I need an editable object page without a create or save button, as there is nothing to save or create. The user can fill the fields manually or fill them via choosing a Dataset from DB and by pressing a Button "Assemble Product" I'm calling a BAPI on a customer on-premise. Everything works fine so far, except for the display of the button, which is just confusing the user.

Do you have any Ideas? Is this scenario so uncommen? A scenario, where a user can edit the fields in a mask but don't creat or save any dataset.

Hi Sebastian,

I have created a simple sample myself using a static action to reproduce your problem.

The reason why no edit button is there, is because you have not created an entity with your implementation shown above.

The framework will try to read data from the RAP BO based on the keys that are returned in the result return table.

You would first have to use EML to create a new entity in your RAP business object.

Then you can use the keys returned in mapped to fill the result return table.

Hope this helps.

Kind regards,

Andre

Hi Andre,

thanks for you support. Unfortunately the logic only works for managed scenarios. I have an unmanaged scenario.

My actual task is an object page with a button that triggers data processing in a connected on-premise system. The data records can either be loaded from the DB/entity or entered directly. This means that saving the data is not intended or desired. Therefore, no Create or Save button should be displayed. Do you have any idea how such a scenario can be implemented?

Best regards,

Sebastian

By the way, thank you for the RAP Generator and your blog posts! These are an invaluable help to me.
