You can have a module activated so that you can synchronize your Supplier with your ERP system.

Delogue imports Supplier data into Delogue from external web service. 

There is a nightly (i.e. GMT 00:00) automated process for this.
This process will call client web service on the basis of Supplier’s Id.

Other suppliers’ details in Delogue will get updated from data provided by client web service.

Once it is activated - then on Admin-Suppliers you will see an extra button "Supplier Sync"

You can read the full documentation here:

It is in the section called "Import Suppliers"
