Hi @Dave Wilson​ %run or dbutils is not supported in DLT. This is intentionally disabled because DLT is declarative and we cannot perform data movement on our own.

To answer your first query, there is unfortunately no option to make the utils notebook run first. The only option is to combine utils and your main notebooks together. This does not address the reusability aspect in DLT and we have raised this feature request with the product team. The engineering team is working internally to address this issue. We can soon expect a feature that would address this usecase.

Thanks.
