I have seen some discussion about using alternate keys to prevent duplicate detection in portals.
I need to prevent users from adding the same entry twice in to a table.
Example,
User skills table
Lookup - UserName
Looup- SkillName
I need to ensure the same user does not enter the same skill twice via portal form.
Any ideas?
Thanks
Hi @MichelleH
Alternate keys will definitely work. Official reference below
https://docs.microsoft.com/en-us/power-apps/developer/data-platform/define-alternate-keys-entity
In some cases, duplicate detection rules will help but alternate key is the easiest way.
Hope it helps.

Either use an Alternate Key (applies to everything not just Portal) or write a Plugin or Custom Workflow Activity and set up to be synchronous (real-time) that will query the existing data to check not a duplicate. Could also use a Custom Validation on the Portal and make either call via Portal Web API or (the older) call a Web Page that returns JSON results.
