Upload Supplier/Vendor list in SAP SRM

Hello Experts,

We are in SRM 7.13 implementation and has requirement to use Supplier list concept of SAP SRM for SOS determination.We need to upload list of supplier with the product catergory mapping as the intial load.

I hope that other project had the same requirement and would like to know the approach taken to handle this requirement.

I have the below information :

1) Supplier list is stored in BBPD_PD_INDEX table.

2) We can use t-code BBPAVLMAINT to mainatin the AVL.But t-code BBPAVLMAINT does not exist in SRM 7.13.

Please provide your suggestions.

Thanks,

Ankur Goyal
