Changeset processing in CAP Node.JS

[#1]

Hello,

We are porting a oData V2 Fiori project to use a CAP service instead. The CAP service is setup to receive the request and make a call to a on-premise system from BTP. While we can GET entity data, we are not able to receive POST changeset requests that the Fiori application sends. The requests in the changeset req seems to arrive at the server,js already split into individual requests.

Can CAP handle changeset requests? If so, can you please point us to some info.

Thanks for your time

I'm trying to set up something similar, where I want to select multiple items and use an action to process them together.

Even when using the ChangeSet option, the action logic is executed separately for each item, however, I've noticed that the HTTP header 'x-correlation-id' is the same for all selected items.

Before going ahead, I'd like someone else to confirm: can I use this header to identify all items that were selected?

See the annotation and the custom logic below:

{
    $Type : 'UI.DataFieldForAction',
    Label : 'Batch Action',
    Action: 'ApiService.batchAction',
    InvocationGrouping : #ChangeSet
}

this.on('batchAction', async (req) => {
      console.log('batchAction begin');
      console.log(req.headers['x-correlation-id']);
      console.log(req.params);
      console.log('batchAction end');
});

Regards,

Pedro
