The [Manual Matching Webapp](web_app:oKmxgwi) enables manual approval or rejection of pending matches. 

It allows reviewing matches individually ( **focus table** ) or through an overview ( **full table** ). Users can use the dropdown button to flag matches and add comments if needed.

## Focus Table

Users can select the ID from the primary dataset they want to review by using the dropdown or by typing the ID. The page will update based on the selected ID.

Users can scroll down to view more matches and click the button in the bottom right to navigate to the next page if needed.

## Differences between 1-to-1 and 1-to-many reconciliation 

-  **One-to-one** : If a match is approved manually in the webapp, other potential matches for the same primary or secondary observation are automatically set as rejected. Only one match is allowed by primary_id or secondary_id.

-  **One-to-many** : If an observation from the secondary dataset is set as a match, then if the same observation is present somewhere else in the web app, it is set as rejected. However, the user can still unselect it and overwrite the previous selection.
