foreign key to be added to cds entity

Hi,

I need some help related to creating foreignkey to one entity and how the data is displayed based on the foreignkey.
this to be achived by CDS.

Example:
Employee and Depatrment are two entities.
both contains DeptNo field is common, which is Primaykey on Department entity.
i want to display the data from both Emp and Dept entiies.

i check the lookup type in CDS is this the way to create foreign key to be added to cds entity.

 

Thanks,

Siva

Hi siva123,

 

Yes, you could create a Relationship from Employee entity to Department entity.
Then you could select the DeptNo from the Department entity and also show it on Employee entity.

 

Please check this documentation for more details:

Re: foreign key to be added to cds entity

Hi,

I have two questions concerning LookUps in the CDS/PowerApps.

I have 2 Entities in my CDS: Machine and Incident. They are connected via a "Relation" in the CDS.
I now have a problem with querying it:

In my App i have a gallery displaying all my machines, besides the machine-gallery, there is another gallery displaying the incidents. All i want is that the incident-gallery shows only the incidents that belong to the machine selected in the machine gallery.
My approach was to set the filter to the Incident Gallery like follows:
Filter(Incidents; Machine_.PrimaryId = MachineGallery.Selected.PrimaryId)

This statement does work like intended, i get this "blue waves" however that i can only execute the query locally.

1) Is there another way to realize a query like this? If yes, how?
2) Wouldn't it be easier if the "Lookup-Field" inside the (in my case) Incidents Entity just contained the PrimaryId of the Machine in either string or int format (much like a foreign key in SQL works) instead of referencing whole machine-object?
The Filter "Filter(Incidents; pmMachine = MachineGallery.Selected.PrimaryId)" - which was my first intention - didn't work.

It's very unfortunate in my opinion that the CDS and PowerApps together are not capable of delivering basic querying functionalities and i really do hope that this soon gets better.

Thank you in advance
