Input Locators
In order to use the Line Item Matching Locator, an input locator that returns purchase order numbers is required. The success of the Line Item Matching Locator is dependent on the success of that Purchase order input locator. If the results of that locator are not good, then Purchase order discovery is needed so additional records can be found from the database for the same Vendor.
If there are problems finding purchase order numbers on your documents, try to include a locator that finds the Vendor ID and select it as the Vendor ID locator. If you use the Vendor ID locator, the purchase order numbers are found based on all possible Vendor IDs delivered by the Vendor ID locator. The total number of Vendor IDs returned can be affected by changing the Minimum confidence for the Vendor ID locator. The higher the confidence, the fewer results.
