Hi Stempien,
I think the problem is due to that you don't execute specific reports to prepare SPL HANA search context in advance. You can find these information in chapter 2.5 Overall Implementation Information in SAP Global Trade Services 11.0 Master Guide:
Step 11: Execute the program/SAPSLL/SPL_HANA_SPLMD_CONVERT via transaction code SE38 in the SAP GTS system.You use this program to concatenate names and streets addresses of sanctioned party lists into the complete names and the complete streets addresses separately for the SAP HANA Fuzzy Search in Sanctioned-Party List Screening.
Step 12: Execute the program/SAPSLL/SPL_HANA_VIEW_CREATE via transaction code SE38 in the SAP GTS system. The implementation of term mappings and stop words inside the SAP HANA Fuzzy Search is not aware of a client column; therefore, this program creates SQL views to select the term mappings and stop words of a given client, respectively.
Best regards,
Hualin
