MSC1N classification data

Hi,

I would like to seek the expertise to automate the data upload for MSC1N. I have tried some function module e.g OIG_BATCH_MASTER_DATA_MAINTAIN, it would create the classification data in MSC1N but u need to maintain the data manually,. is there any way to update the classification data automatically?

is there any BAPI/FM available that i can put the data and it will create classification for me in MSC1N/MSC2N?

thanks for the help as im out of ideas now.

thanks
