Batches require significant special handling, which differs depending on whether Financial Batch Manager is enabled. Note that it will not be enabled for most people, and when not enabled, batch is optional (and you probably won’t want to submit anything for it).

The following rules are applied to the specified batch for a tenant that has Financial Batch Manager turned off:

Batch specification	Result
A batch Id that references an existing batch is specified	Referenced batch is used
A batch Id that does not reference an existing batch is specified	Error message is returned
Only a batch name that references an existing batch is specified	Referenced batch is used
Only a batch name that does not reference an existing batch is specified	A new batch with the specified name is created

The following rules are applied to the specified batch for a tenant that has Financial Batch Manager turned on:

Batch specification	Result
A batch Id that references an existing batch is specified	Referenced batch is used
A batch Id that does not reference an existing batch is specified	Error message is returned
Only a batch name that references an existing batch is specified	Referenced batch is used
Only a batch name that does not reference an existing batch is specified	Error message is returned
No batch is specified	Error message is returned
