Composite Primary Key in CDM

[subhash]

It would be helpful to validate entries if multiple fields together act as primary key(Composite primary key)

What would be the workaround if i want to find the record in an Entity which has LastName and FirstName as primary Keys ?  I need to be able to retrieve the record to be loaded to the form for editing.

Hi @subhash - while the primary key itself is always a GUID in CDS, you can define a multi part composite key - you can read more details here : https://docs.microsoft.com/en-us/powerapps/maker/common-data-service/define-alternate-keys-portal
