As organizations finally move off Dynamics GP, many discover that Accounts Payable and the General Ledger are where migration projects succeed—or stall. This session dives into advanced, field-tested patterns for moving AP and GL from GP to Business Central with confidence, accuracy, and auditability. Attendees will see how to handle open and historical AP documents, preserve 1099 and vendor history, reconcile subledgers to the GL at cutover, and redesign posting groups and dimensions so that legacy GP structures map cleanly into Business Central without losing reporting fidelity. The session also covers typical failure points such as applied documents, discounts, reclasses, and multicurrency, along with validation strategies and test approaches that keep finance teams in control of the outcome. You’ll leave with a practical checklist and migration pattern library you can apply directly to upcoming GP-to-BC projects.
