Block the creation of vendors via the "extend vendor" function

Question

Is it possible to block the creation of vendors via the "extend vendor" function?  Currently, a number of vendors have been created in this way and are 'shared' across different markets.  This has created a control risk on master data, so I am investigating if it is possible to restrict the process.
Please suggest
Thanks

Hi:
           Initially your requirement was just to detain user from creating vendor using reference vendor as given in XK01 under reference (Vendor number and co code & Purchasing organization). Through SHD0 you were able to suppress these three fields ( if i am right? correct me here). If its Ok then system has stopped you from creating vendor using reference of another already created vendor. As far main vendor number and co code and purchasing org fields are concerned that appears on the top of XK01 please note that Vendor number field is only used when you use external number range for this vendor account group ( check number range assigned to the vendor account group in OBAS and then check it in XKN1 if is set as external or internal number range). If you have activated internal number range then nothing needs to be given in Vendor number field and system will generate vendor number internally and this can be suppressed otherwise if you are using external number range the system will create vendor as given by you in Vendor in main screen of XK01. Hence it depends on the process you are using in your company for vendor master data creation.
