Supplier is being created with system ID as Buyer_XXX and being associated to a partition supplier.

There are two causes why the system creates a Common supplier with Ariba Unique ID- Buyer_xxx.

1. If partition supplier data is loaded before the common supplier data on the realm.
2. If Common supplier data is not replicated to the child realm and before that you load partition supplier data on the child.

In both cases the Partition supplier does not find the correct Common supplier with which to associate themselves, so the system generates a new common supplier with incorrect ID, Buyer_xxx.

The AribaNetworkOrganizationSyncOption parameter can also create Buyer_xxx ids.

We can fix this issue by avoiding the above mistake or if it is incorrectly loaded we can correct it by following these steps :

1. Export the Supplier Organization files from the system;
2. From the SupplierIDs.csv, remove all of the domains (sap, networkid, duns, etc.) and values other than buyersystemid for suppliers where buyersystemid values are buyer_xxxx.
3. Reload the resulting file (and the exported SupplierOrganizations.csv) back into the realm. The outcome of this action is:
   
   
   1. The buyer_xxx suppliers will not have any other domain or value other than buyersystemid.
   2. This operation will break connection with the Partitioned Supplier and Supplier Locations.
      
      
4. After the successful completion of step 3, reload again exactly the two same files, this time in deactivation mode. This should deactivate the suppliers with a buyer_xxx value for buyersystemid.
5. After step 4 is verified, reload the correct SupplierOganization.csv and SupplierIDs.csv with the correct domains and values.
6. After Step 5, reload Supplier.csv and SupplierLocation.csv exactly as loaded before, so the connection to the top object can be re-established.

IMPORTANT: This operation, most likely, will affect the catalogs of the system, if these are related to suppliers with the buyer_xxxx value. Once the corrected (new) supplier is loaded, the catalog needs to be reloaded/relinked to the correct supplier entity.

We do not encourage you to engage on these corrections in the production environment right away. Please use the test environment to verify these steps with one supplier. Once you understand the process, replicate it in the production realm.

If a few suppliers need to be corrected, it can be done manually too.

You can go to supplier manger and search for the supplier with the correct Common Supplier ID and associate it will the partition supplier attached to the incorrect Common supplier.

Once correct linkage happens, please, deactivate the supplier with the incorrect system ID (Buyer_xxx).
