Assign a new document to a batch
What It Does
Default selection connects document creation to saved business-unit routing. It chooses a stream and validates that stream current collection before Transactions writes the document. Pro forma work and an absent default require caller-specific handling.
The Flow
When Something Fails
Selection can return no choice or an eligibility refusal without writing anything. The document caller owns the final required-batch response. The unused native order hook is documented as a carried option rather than a built Commerce integration.
Open Design Questions
Transactions must supply complete companion facts and define absent-selection behavior for each document kind.
