AA (Arrangement Architecture) in T24

Arrangement Architecture is T24's product-handling framework that replaced the legacy account-based model. Under AA, each product (loan, mortgage, credit card, overdraft) is modelled as an arrangement with property classes (interest, commitment, dated conditions, etc.). Working with AA means building correctly structured AA.ARRANGEMENT.ACTIVITY OFS messages — the exact format this tool helps you produce.
