In such cases, the New Vendor Registration remains in an “approved” status instead of moving to a “connected” status. This guide provides step-by-step troubleshooting instructions to help you identify and resolve issues with vendor connections. --- #### **Troubleshooting Steps** ### **For Payers Manually Uploading Supplier Files** 1. **Confirm Registration Status** - Ensure the New Vendor Registration is in an **“approved”** or **“processed”** status. Only registrations in these statuses can proceed to the “connected” status. 2. **Verify the TIN Match** - Compare the TIN (Tax Identification Number) on your supplier file with the TIN in the New Vendor Registration. - Ensure the TIN values match **exactly**. - If the vendor’s TIN starts with **0**, ensure your spreadsheet is formatted as **text** to preserve the leading zero. 3. **Check the Request ID** - Ensure the **Request ID** on your supplier file matches the Request ID on the New Vendor Registration. 4. **Review Vendor Number and Site Code** - Verify that the **vendor number/site code combination** on your supplier file: - Has not been used for another vendor connection. - If the vendor was previously registered in PaymentWorks, confirm that their supplier profile isn’t already connected. 5. **Check for Unicode/Foreign Characters** - If a “UTF-8” error occurs during upload, it indicates the presence of unsupported unicode or foreign characters in the file. Remove these characters and try uploading again. --- ### **For Payers Using Automated Supplier File Integration** 1. **Review ERP Logs** - Check your ERP logs for errors during the automated file transfer process. 2. **Pinpoint the Integration Issue** - Determine where in the integration process the issue occurred: - Check if vendor registration data in PaymentWorks synced into your ERP system. - Confirm if the issue occurred **before** or **after** this sync. 3. **Check Supplier Upload in PaymentWorks** - Navigate to the **Supplier Upload page** to confirm the automated file upload occurred successfully in PaymentWorks. 4. **Confirm Supplier Profile Creation** - Verify under the **Suppliers tab** in PaymentWorks that the vendors from the upload file have had supplier profiles created. --- #### **Additional Steps** - **Retry the File Upload** - If no issues are identified, re-upload the file to attempt a second connection. - **Contact PaymentWorks Support** - If the connection still fails after troubleshooting, contact [PaymentWorks Support](https://help.paymentworks.com/contactsupport?hsLang=en) for further assistance. --- #### **Important Notes** - **File Re-Upload** - Re-uploading the file may resolve the issue if it was caused by a temporary system or formatting error. - **Data Integrity** - Double-check data integrity in your supplier file to ensure there are no formatting errors or inconsistencies. -
