trying to understand a concept 'Extend'

[KY101]

why and when do we need to extend "Supplier to Purchase Org " ? To accomplish …?

Or whenever we "Extend to" something do we try to accomplish something specific ?

I am in pains to understand the 'extend' concept and need all the direction I can get to understand it. 

Thanks a lot!

Hello @KY101 

Vendor master data is maintained on several organizational levels. It has a central data e.g. address, data on company code level (all the FI related stuff) and data on purchasing organization level (info related to purchasing). 

If you want to use a vendor number for a specific purchasing organization level, you need to create the vendor data on the purchasing organization level or in other words extend the vendor to the purchasing organization level.

The same concept works for materials that are maintained on central level, plant level, storage location level, sales area level etc. 

Best regards
