Munis Web services return no value when calling apwsvssh_get_type as no Vendor Type Codes exist

1. Verify in Munis that Vendor Type Codes have been setup under Financials→ Accounts Payable→ Setup→ Accounts Payable Miscellaneous Codes
   1. If no Vendor Type Codes are found listed use the following article for setup: How to add a vendor type code
2. Once the necessary codes have been added to Munis the VSS Default Settings page will resolve properly
