When you are collecting information on VAT in Concur and have elected to show the tax information in the tax tables that Deltek provides on the Expense Entry screen, you may see no amounts or incorrect attribution of tax codes.
This is only relevant when you have the "Enable VAT same Line on Expense Report" option in your Configuration InfoCenter/Hub.
Steps for resolving this are:
1) Ensure the tax code you are wishing to see is in Deltek and matches the codes you are collecting for in Concur.
2) Submit a support ticket to support@blackboxconnector.com to request the latest ExpenseToEK stored procedure be loaded in your Deltek environment and that your connector instance is refreshed to include column 227 mapped to the "CustCVATAllocationTotalTaxTransactionAmount" column from your SAE file.
