Before you can use the application areas within Compliance Management and Customs Management, the documents that are created in the feeder system prior to, or during, an import or export process (such as purchase orders, sales orders, and billing documents) require counterparts in the SAP GTS system. Therefore, these documents must be replicated in SAP GTS in the form of customs documents, customs shipments, and customs declarations, depending on the application area they are meant for.

To ensure that all documents required for the various application areas in SAP GTS are transferred, you have to flag the respective document types as relevant for SAP GTS in the feeder system. In the Customizing of the SAP ECC system, choose Sales and Distribution→Foreign Trade/Customs→SAP Global Trade Services - Plug-In→Control Data for Transfer to SAP Global Trade Services→Configure Control Settings for Document Transfer. In SAP S/4HANA, choose Integration with Other SAP Components→Integration with Governance, Risk and Compliance→SAP Global Trade Services→Control Data for Transfer to SAP Global Trade Services→Configure Control Settings for Document Transfer.
In an SAP S/4HANA feeder system, you can restrict document transfer using the company code in addition to the document type (Activation Level field). You specify the relevant company codes in the Document Type/Company Codes subfolder.
You will find three application levels for each basic process: MM0A, MM0B, and MM0C for inbound processes; and SD0A, SD0B, and SD0C for outbound processes. Each application level groups together document categories according to their respective function in the process. For example, MM0A is the application level of purchasing documents.
From the details of each application level, you can see for which group of application areas in SAP GTS the documents can be used. For example, you can transfer sales documents (application level SD0A) to SAP GTS to allow the replicas to be checked in Compliance Management. The option to transfer documents for Risk Management (letter of credit and restitution application areas) is only relevant for SAP GTS 11.0.
Note
A detailed description of how to set up document transfer from the feeder system to SAP GTS is provided in the Integration Guide.
