What happens if I send the same "Transaction id" multiple times to track purchases in Google Analytics Ecommerce?

I am reading the documentation at https://developers.google.com/analytics/devguides/collection/analyticsjs/enhanced-ecommerce and they provide an example of code to measure transactions:

ga('ec:addProduct', {               // Provide product details in an productFieldObject.
  'id': 'P12345',                   // Product ID (string).
  'name': 'Android Warhol T-Shirt', // Product name (string).
  'category': 'Apparel',            // Product category (string).
  'brand': 'Google',                // Product brand (string).
  'variant': 'black',               // Product variant (string).
  'price': '29.20',                 // Product price (currency).
  'coupon': 'APPARELSALE',          // Product coupon (string).
  'quantity': 1                     // Product quantity (number).
});

ga('ec:setAction', 'purchase', {          // Transaction details are provided in an actionFieldObject.
  'id': 'T12345',                         // (Required) Transaction id (string).
  'affiliation': 'Google Store - Online', // Affiliation (string).
  'revenue': '37.39',                     // Revenue (currency).
  'tax': '2.85',                          // Tax (currency).
  'shipping': '5.34',                     // Shipping (currency).
  'coupon': 'SUMMER2013'                  // Transaction coupon (string).
});

In the ga('ec:setAction', 'purchase' section, the Transaction id (string) is required. For some reason in my code, something specific to my systems that I may have to fix later, but the point is that there is a possibility that in extraordinary situations, my code could send the same Transaction id (string) multiple times. In the code above, it means that for different transactions, I could be sending 'id': 'T12345' multiple times. What would happen in that case? How would Google Analytics report multiple transactions with redundant transaction IDs?

GA doesn't require uniqueness on transaction ID, so you will see all of your transactions, even if you have multiple transactions with the same ID. You will see a value greater than one in the Quantity column of the Conversions > Ecommerce > Transaction report when there are duplicates.

If two transactions are reported in the same session for the same user with the same ID, the transaction should be* de-duplicated, though I haven't found this to be entirely reliable. It doesn't sound like this de-duplication applies to your situation, since presumably you are talking about different users and therefore different sessions.

*Sorry for the vagueness of "should be" - I've seen it happen, and it has been reported by other users, but I can't find it in GA documentation.
