Generating and processing ERN batches
When a record company or aggregator wants to add a release into a new batch of releases to be communicated to a DSP, the record company or aggregator needs to ensure that that the batches containing that Release are closed in the exactly the same order they have been created.
If the record company or aggregator cannot guarantee this, it must ensure that a release that is being added into an open Batch is not in another open batch to the same DSP.
The reason for this rule – this is expected to be added into the next version of the ERN Choreography Standard – is that the receiving DSP might otherwise ingest the release information in the wrong order. And that might, for example, lead to the making available of a Release that has already been taken down.
