BAPI or FM to copy Material (MM01)?

Dear Experts,

I am finding difficult to locate a BAPI or FM that would create a New Material referencing a Old Material. This facility is provided by MM01. I managed to locate few BAPI's but they don't have a interface to capture the Old Material.

1. /AFS/BAPI_MATERIAL_SAVEDATA

2. BAPI_MATERIAL_SAVEREPLICA

3. BAPI_MATERIAL_SAVEDATA

If you find a BAPI or FM please pass it on. If you could include some sample data.

Thanks,

Sri
