As we know, SAP doesn't provide the report to display WHT for customers and vendors. Below, there're some alternatives:
--> Copy the report S_P00_07000134 for country's client and customize it;
--> Check the tables LFBW,LFB1 & LFA1;
--> Do a query by SQVI and merge BSIK vs WITH_ITEM and then assign to a transaction;
--> Create a new report.
I think the third option is better than other.
