One solution is to get the runId,jobId details using notebook context in child notebook and return these values using dbutils.notebook.exit to parent notebook.

%scala
val jobId = dbutils.notebook.getContext.tags("jobId").toString()
val runId = dbutils.notebook.getContext.tags("jobId").toString()
 
 
 
%scala
import com.fasterxml.jackson.module.scala.DefaultScalaModule
import com.fasterxml.jackson.module.scala.experimental.ScalaObjectMapper
import com.fasterxml.jackson.databind.ObjectMapper
 
val jsonMapper = new ObjectMapper with ScalaObjectMapper
jsonMapper.registerModule(DefaultScalaModule)
 
dbutils.notebook.exit(jsonMapper.writeValueAsString(Map("jobId" -> jobId, "runId" -> runId)))
