What is the difference between one-way and bi-directional integrations?
One-way integrations would be, for instance, from your ERP system, when you only want to replace the data in the CRM with data from the ERP system but you do not want any data coming from the CRM to the ERP. Bi-directional integrations are when data can flow from the ERP to the CRM and data can go from the CRM to the ERP system – the only important point would be to establish user rights and field permissions before you setup any process.
