Which feature associates an Order Entry transaction with the appropriate icon on the overview map?

The feature that associates an Order Entry transaction with the appropriate icon on the overview map is the workflow category. This categorization allows the system to visually represent different types of transactions using specific icons on the overview map, facilitating easier identification and navigation for users. By defining workflow categories, distinct business processes can be highlighted, ensuring that users can quickly recognize the status and type of each transaction as it aligns with the overall workflow in Sage Intacct.

The other options do not have the same functionality; for instance, while category classification, transaction code, and item description are important in managing and processing orders, they do not directly influence the visual representation of transactions on the overview map.
