Hi Sasikanth,
XML file Tariff loads can be uploaded only in GTS.
Once you upload the tariff files, you will upload the product classifications using the program
/SAPSLL/MARC_UPLOAD_R3 and generally you would use the maximum of 30000 records per load.
Once the product classification upload is complete, you will use /SAPSLL/STAWN_RETRANSFER program to transfer all the classified materials along with the assigned Tariff code.
Once you have done that, you need to go to ECC system and execute the program /SAPSLL/STAWN_RETRANSFER_R3 to update the entries into MARC table.
Note: When /SAPSLL/STAWN_RETRANSFER program runs, classification related entries will be put into T604 and T604T tables and when the /SAPSLL/STAWN_RETRANSFER_R3 gets executed entries will be updated against MARC table for all the respective material+Plant combinations(w.r.t country).
Please do let me know if you have any questions. Thanks.
Regards
Raj
