Role: SaFi bank

Objective:

want to create a concise/not-too-long reference number for every transaction

Reason:

Execution steps (Happy path):

External dependencies:-

Alternative scenarios:-

Acceptance criteria:

• Every parent transaction has its unique reference number, 8+ digits long

  • for TX containing also fees, only one ID should be issued, i.e. no separate ID for fee entry

  • for a split transaction, only one ID should be issued for the parent TX and not the child transactions

• This customer-facing ID is a simplified version of the existing UUID (very long, not readable)
