To enable the Total Landing Cost (TLC) feature, you must map the landed cost types from SAP Ariba (e.g., freight, duty, insurance) to the corresponding pricing condition types in the SAP ERP or S/4HANA system. This mapping is performed within the SAP Ariba Cloud Integration Gateway (CIG) mapping tool for the PurchaseOrderExportRequest transaction. A lookup table is created and maintained to translate the LandedCostType value from the incoming Ariba cXML document to the correct CONDTYPE value in the target ERP IDoc (ORDERS05). This ensures that all associated costs are accurately reflected in the purchase order created in the backend system.

B. Real-Time Budget Check: This feature is configured as a separate, synchronous web service call from SAP Ariba to the ERP system and does not involve a lookup table in the PurchaseOrderExportRequest mapping.

C. Amount-Based Purchase Order: This is a standard functionality handled through item category mapping (e.g., mapping to item category 'B' for limit items) rather than a specific feature-related lookup table.

D. Withholding Tax: While tax codes are mapped, the enablement of the withholding tax feature itself is primarily controlled by a specific integration parameter (ENABLEWTAXPO) in CIG, not a lookup table.

SAP Help Portal, SAP Ariba Cloud Integration Gateway Documentation: "Integrating SAP Ariba cloud solutions with SAP ERP or SAP S/4HANA", Section: How to configure total landed costs for purchase orders. This guide explicitly states, "You must map the landed cost types in SAP Ariba cloud solutions to the condition types in SAP ERP or SAP S/4HANA. You can use a lookup table to map the landed cost types to the condition types." It details mapping the LandedCostType from the cXML to the E1EDP05 segment's CONDTYPE field in the ORDERS05 IDoc.

2. SAP Help Portal, SAP Ariba Cloud Integration Gateway Documentation: "Integrating SAP Ariba cloud solutions with SAP ERP or SAP S/4HANA", Section: How to configure real-time budget check. This section describes the configuration of web services (e.g., ARBCIGBUDGETCHECKASYNIN) and RFC destinations, confirming it is a separate process from the PO export mapping.

3. SAP Help Portal, SAP Ariba Cloud Integration Gateway Documentation: "Integrating SAP Ariba cloud solutions with SAP ERP or SAP S/4HANA", Section: How to configure withholding tax for purchase orders. This document clarifies that the feature is enabled by setting the parameter Application.Procure.EnableWtaxForPO to Yes in CIG, which is distinct from maintaining a lookup table for a feature.
