Run a Load job only if the Stage job that loads the staging table used by the Load job has completed successfully.

Run the Load job for a parent table before you run the Load job for a child table.

If a lookup on the child object is not defined (the lookup table and column were not populated), in order to successfully load data, you must repeat the Stage job on the child object prior to running the Load job.

Only one Load job at a time can be run for the same base object. Multiple Load jobs for the same base object cannot be run concurrently.

You cannot run a load job on multiple parent base objects in parallel if the parent base objects share a common child base object.
