Most companies export only a few dual-use items. Nevertheless, compliance with the export control regimes based on international agreements has to be ensured throughout the sales process.
SAP GTS identifies dual-use items in an export document from their classification on the Legal Control tab of their product master data. Users can check the classification on the Classification tab at line item level.

If a product is classified as a dual-use item, the system tries to find a suitable license for the export of this product to the country of destination. If the search fails, the system preventively blocks the line item. This block can only be lifted by assigning a license.
As a rule, license determination is successful at the first attempt if a general export license, a license exception or a similar license type is available for the planned export. In contrast, individual licenses first have to be applied for, and it might take time for the authorities to issue them.
It therefore makes sense to schedule the /SAPSLL/CUHD_MASS_REFRESH_EXIM program for background execution at regular intervals. This program can also be started using the Recheck Documents app. The system repeats license determination for the selected documents and assigns new or changed licenses if possible.
Blocks can also be lifted by manual license assignment using the Change Control Data for Documents app. However, the manual assignment of licenses to blocked line items should remain the exception.
Caution
Using this app, factually inaccurate assignments are possible.
