% Complete Gets Out of Sync

Question: Why do % complete values not match between MS Project and Jira after synchronisation?

Answer: % complete values may not align between MS Project and Jira due to interdependent field mappings and MS Project's internal recalculation logic. Fields such as Actual Work, Start/Finish dates, and Work can affect % complete, especially when multiple fields are mapped simultaneously. To avoid inconsistencies, map only one of the interdependent fields (e.g., % complete or Actual Work).
