DSN - Tax Codes

[sunisakokeaw]

Hi Experts,

at our customer we have different tax codes for the incoming tax (see screenshot) of the supplier invoices.

Some of these tax codes have the same tax rates. For example D5, E1, etc. with 19%

We are now not clear how to maintain the table (transaction OBCD), to store the correct tax code when posting the invoice in SAP.

Thank you in advance for the support.

Hi Sunisa,

there are multiple good solutions on how to configure tax code assignment. You need to have a session with customer to determine what is the best approach.

Customer should guide you on how do they automatically assign tax codes today – it is okay to ask the customer.

Usually what customer does:

1. Customer has tax code on the PO and it is copied from PO to Invoice
   • Non-po invoices have manual tax code assignment alongside with accounting
2. Customer has some automation logic that they use today
   • try to replicate the logic by using OBCD table or extend the table and the lookup logic
3. Customer has no logic/automation
   • Park all invoices and have users assign tax code manually before posting
4. Customer would like to have a supplier selecting tax codes on invoices
   • This is a bad practice and not recommended although possible
   • You can create different tax types on Ariba Network by using category ‘Other’
   • These different tax types can be used in OBCD as a lookup key driving tax code assignment
