  title: Business Central Upsert an Item
  summary: Find an item by number and update it if it exists, otherwise create it.
  description: >-
    A common Business Central catalog-sync pattern. The workflow searches the
    company item list for an existing item whose number matches the supplied
    value, then branches: when a match is found it patches the existing item,
    and when no match is found it creates a new item. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
