Hi @jeremy98 ,

When a DLT pipeline creates a table, this table can only be written to by the pipeline that created it. If another pipeline tries to write data to this table the pipeline will error.

The solution is quite simple, parametrize your DAB template in such way that each developer during DAB deployment to DEV will have its own dedicated catalog. You can refere to below article when this approach is explained in details:
