How do I convert a Fiori Elements List Report to be Draft Enabled?

[michael_piehl]

I have an existing Fiori Elements List report. The services were generated from SEGW, OData V2, and I am using annotations to control all the elements of the display.

I have several ui.lineitems on the object page that I want to be able to use change/display and inline creation. I understand that inline creation is only available for draft enabled applications, but I have been unable to determine how to convert my existing application to be draft enabled. I have looked through the blogs/questions and I Have been unable to find anything that shows me how to set something as draft enabled. What annotations need to be added? do I need to add new entities (DraftAdministrativeData???)

If anyone can point me to documentation or walk-thrus to help me convert my application, I would be very greatful,

Mike

Hi Mike

I used the inline editing of a table in a similar scenario as yours without draft.

My setup:

- SEGW using CDS via Referenced Data Sources
- SmartTable to display / edit Table
- Save with oModel.submitChanges() -> this triggers a $batch call with all modified
records (changesets) in the body of the oData call -> this again triggers
the changeset methods of your DPC_EXT class.
- Redefine the (/IWBEP/IF_MGW_APPL_SRV_RUNTIME) methods changeset_begin,
changeset_end and CHANGESET_PROCESS for your DPC_EXT class
- You could code all your business logic in these methods. Be carefull with the "commit".
- As I wanted to re-use my already existing code in my single record "update_entity",
I used the "deferred mode" which calls my "update entity" methods. To achieve this
behaviour I just did not redefine the CHANGESET_PROCESS. You are not allowed
to commit the "update entity". Do the commit in the changeset_end.

If you want to know more about deferred mode:

thanks Paul,

Currently, when I press the create button, I do not get the blank line in my table to add values into anything. I only get the error

Cannot set properties of undefined (setting 'createNonDraftInfo)

Here is the other question I asked that started all of this: https://answers.sap.com/questions/13998183/inline-create-in-object-page-cannot-set-properties.html?u... (this link contains my metadata and manifest, if that might help).

I'm already using the changeset_begin and changeset_process methods for other buttons. My problem seems to be that when I press the button, I don't even get the option to enter some values and press save. Did you need to create a different button, instead of the standard SAP button?

Thanks for all your help,

Mike
