In SAP ECC and SAP S/4HANA, organizational units such as company codes, plants, or sales organizations are the main basis of process-related system configuration. Many Customizing settings in Logistics and Accounting are dependent on organizational units.
There are no organizational units in SAP GTS. From the perspective of system configuration, the legal regulations take the place of organizational units. Most of the Customizing settings in SAP GTS are used to configure legal regulations for the individual application areas.

From a technical perspective, legal regulations are alphanumeric keys that are defined in Customizing of the SAP GTS system and are linked to a large number of control parameters. Most of these control parameters depend on the application area in which the legal regulation is to be used. Thus, for example, you define the scope and strictness of the address check at the level of a legal regulation for sanctioned party list screening.
It is not always appropriate to use the legal regulations contained in delivery Customizing without making changes to them. It is also possible that there is no model that meets your requirements. In such cases, you create your own legal regulations in the customer name space. To do so, in Customizing of the SAP GTS system, choose the menu path SAP Global Trade Services, edition for SAP HANA → General Settings → Legal Regulations → Define Legal Regulation.
The configuration of the legal regulations contained in delivery Customizing corresponds to the legal situation at the time of delivery. Legal changes that take effect after this time may result in changes to the system configuration. If a legal change has resulted in adjustments to the program code, you can update your system by implementing support packages. Delivery Customizing is also constantly adjusted in this way. In any case, you must ensure that knowledgeable employees keep track of relevant legal changes and, if necessary, initiate configuration changes or make configuration changes themselves.
