Choose split-order numbers
Standard Increment IDs gives each result the next normal Magento order number.
Base Increment ID with Suffix reserves one Magento base number and formats every result from it. With {base}-{n} and a start index of 1, a base of 100000123 produces:
100000123-1100000123-2
The format must contain both {base} and {n}. If any generated ID already exists, the extension clears the reservation and tries a new base number up to Max Conflict Retries. Submission stops if it cannot create a unique set.
Choose a format that fits the maximum length and validation rules of connected ERP, payment, warehouse and accounting systems. These integrations receive the actual split order numbers, not a separate display-only reference.
