Unmanaged association support for Change tracking

[vishalsharma190596]

Hi Team,

We are using the Change tracking plugin for a production application and need your support to handle the requirements below.

This is how our current Entities look like where the Change tracking works well.

entity CustomerTracker : managed {
    key ID                             : String;
        customerName          : String;
        progress                     : Composition of many CustomerProgress
                                                                  on progress.cm = $self;
}
entity CustomerProgress : cuid, managed {
        cm                                : Association to CustomerTracker;
        progressDate               : Date @changelog;
}

Now we want to introduce another key field in CustomerTracker entity to store the solution area so we can track the same Customers with different Solution areas. Below are the changes with the solution area.

entity CustomerTracker : managed {
    key ID                             : String;
    key solution                    : String;
        customerName           : String;
        progress                      : Composition of many CustomerProgress
                                             on  progress.customerId = ID
                                             and progress.solution   = solution;
}
entity CustomerProgress : cuid, managed {
        customerId                   : String;
        solution                        : String;
        ct                                : Association to CustomerTracker;
        progressDate               : Date @changelog;
}

With this change, the app works well but it is not show any Changes in the Change Tracking Facet.

Thanks & Regards,

Hi @vishalsharma190596 ,

It seems that your second scenario uses multiple keys as the entity's key values. Currently, change tracking does not support multiple keys, and the key name must be an ID.

Hi @Sv7enNowitzki ,

Thank you for your response. Can you please provide if multiple keys will be supported in change tracking in the near future as we need the Change tracking feature in our Production application along with multiple keys.

Appreciate your help.

Thanks & Regards,

Hi @vishalsharma190596 ,

Currently, there is a PR regarding support for multiple keys, but it cannot be approved yet. Personally, I believe we need to change our current model. Because it can not be shown in UI.

Hello @nkaputnik , could you share some updates on the research progress regarding multi-key support?

Best Regards,

Merge this issue into #130 because the problem is the same.
