How to integrate a field in business central having a datatype lookup in dataverse?

Having a field of dataverse table and I am trying to integrate it with business central. Field datatype is lookup when I am trying to integrate this field using PowerShell ISE command this is not integrated into business central.

You’ll need to add the related dataverse table as a custom table in BC. There is a process for pulling Dataverse table definitions into BC. You’ll need to pull in both the related table and this table you show in your screenshot.
Once you’ve done that, you can then setup the Field Mapping in BC.
