You may be aware of US governments attempts to streamline the import/export process in USA by having an electronic “Single Window” IT system by the end of 2016 (Automated Commercial Environment ACE – http://www.cbp.gov/trade/ace). Note 1998947 provides some GTS related ACE information. As mentioned in note, the recommendation from SAP GTS is that effected customers launch a corresponding project at an early stage and familiarize themselves with the ACE requirements because this is a new customs system and not a release upgrade of the existing customs system.
The following Support Package levels are the minimum prerequisite for the use of ACE:
SAP GTS 10.0 Support Package 23
SAP GTS 10.1 Support Package 15
