An other way would be to do a Log-in with Language = RU, and to use t-code se16n to look at table T512T. Delete the number in the "Maximum occurences" box, enter the Country Code for Russia, select EN for Language, and execute the report.
Open an other session and use t-code sm30 to add the required Russian descriptions to the WTs in table view V_T512T.
Note that if the Customer WTs were created with a RU Log-in, then you would have to do the reverse (do an EN log-in and create the WT's Labels).
