Hi @malleswariponn 

Creating an identity column in a table isn't supported in a warehouse in Microsoft Fabric currently. Instead, you'll need to use a workaround technique. The following article describes a workaround technique that generates unique identifiers in a warehouse table. Hope you would find it helpful.

Updated:

According to the messages from the following idea, the support for identity column has been added in the plan. But we haven't received definite ETA for it. Please keep using Fabric and follow the Microsoft Fabric Blog to get the latest updates.

You can use dataflow Gen2 :

to autogenerate new values based on max aspect

Hi @malleswariponn ,

Is there any way you can provide the CREATE statements that you are using for your tables?

Are you using foreign key constraints? The reason I'm asking is because foreign keys can only be used when NOT ENFORCED is used.

You can find more information about this via the following URL: Tables in data warehousing - Microsoft Fabric | Microsoft Learn

Please let me know if this helps.

If not I suggest that you provide the statements of the objects than I would be more than happy to take a look.

Kind regards,

Olivier
