Withholding Tax in Manage Supplier Line Items

[Ayumi]

Dear all

When I have inputed W/Tax Base and WTax Amt in "Create Incoming Invoice" , I inquire about this item for which from Menu > Document > Display , Withholding Tax is displayed on Display Document: Line Item screen.

However, when I inquire about same Item in "Manage Supplier Line Items", Withholding Tax is displayed as 0.

Please tell me how to display Withholding Tax in "Manage Supplier Line Items".

Thanks
