If documents are to be transferred from the legacy system, the following issues have to be considered:

• Before going live with the SAP system, you should create the VAT reporting in your old system. It is not possible to create a VAT reporting in SAP for documents taken over from the legacy system.
• Open vendor items must be taken over with the correct section code allocation if payments to these vendors are subject to withholding tax. SAP FI posts the withholding tax amount in the moment the open items are paid (default setting for Korea). In order to allocate the withholding tax amount to the correct section code, the section code must be entered in the section code field on the vendor line.
