Extracting Supplier master from ECC

Hi Experts

We are using SIM with sourcing and trying to extract supplier master data from ECC.

Can you please let me know the tcode/program in ECC used to extract the suppliers into a CSV file for import into ARIBA ( with respect to SIM with Sourcing )

I managed to find ZARIBA_SSP_MASTER_DATA_PULL  but seems that it is not used for supplier extraction from SIM + Sourcing perspective

Thanks
