DSN - SG INVOICE Tax Exchange Rate Field

[jademichael_din]

Hi Experts,

We would like to know how other Singapore companies who are using Ariba Network Invoicing manage the Tax Exchange Rate for GST compliance. Currently, the Tax Exchange Rate field in Ariba is being defaulted to the value extracted from Bloomberg. Because it already has a value by default, the Supplier may not be able to edit it before submitting the invoice. Our client wants this field to be blank by default so that Supplier will be required to populate it but according to SAP Ariba Customization Engineer for DSN, this field cannot be blank by default.

Hence, the following options were suggested.

1. Have a Custom Message below the Tax Exchange Rate to remind the supplier

2. Create a new custom field – the catch here is that the custom field will be available and required for all suppliers regardless if they are in the same location as the ship-to party or not.

Caveats of the options provided:

Option 1 – Supplier can still ignore the message and not edit the tax exchange rate.

Option 2 – Cannot be mapped to the computed invoice value in the summary/review page. Also may hinder customer in the future if an Ariba upgrade happens and the custom field is not considered.

With this, how do other SG companies ensure that the tax exchange rate is correct?

Hello,

From what we see current customers use the system with functionality 'as-is'.

They have no warning messages or no extra custom fields for invoices that are in currency other than SGD and require GST input.

What definitely happens is that in training materials for suppliers this is mentioned and highlighted.

However if your customer has still doubts and would like to avoid mistakes from suppliers I would propose:

a) create a custom field that is a type with YES/NO answer

b) field needs to be marked as mandatory, meaning supplier always needs to select either YES or NO

c) field would be located on invoice header and would state:

d) 'Please select YES if proposed tax exchange rate is the one you would like to use for this invoice. If not - please select NO and edit value in tax exchange rate field'

e) that custom field would be mandatory, if supplier will not select 'yes/no' supplier will not proceed further with invoice submission

f) custom field would appear only in case of foreign currency on invoice

Lastly:
