When processing orders you might come across the "111 Error in parsing request XML:Error: Datatype error: In element 'PhoneNumber' : Value '' does not match regular expression facet" error.
This error is shown when the Ship-to Phone used in an order is missing or does not have a correct format.
Feel free to follow the step-by-step guide written below or the video guide, as you prefer:
To do so:
1. Find the order through any of the possible ways (after Import Orders, Batches, Order History, etc) as it applies to the case
2. Click the edit button of the order you wish to change
3. Add or Change the Phone accordingly
4. Press Save to apply the changes
If the rest of the information in the order is correct, you will be able to process it.
