Hi @Srikanth Garik​ 

currently DLT is not supported with the Unity Catalog. The latest ETA that I've heard was end of the November.

Please see here for more details:

Referencing Unity Catalog tables from Delta Live Tables pipelines is currently not supported.

You might try to join the Databricks Office Hours tomorrow and ask the question or see if there is any update:
