• Key Concepts: 
  External ID is a unique identifier used to identify a contact in the Emarsys system. It is used to link contacts between the Emarsys system and the SAP CEC-EMA connector. This allows for data synchronization between the two systems, allowing for more efficient marketing campaigns. 
  
  How to use it: 
  The External ID is used to link contacts between the Emarsys system and the SAP CEC-EMA connector. This is done by mapping the External ID field in the Emarsys system to the corresponding field in the SAP CEC-EMA connector. Once this mapping is complete, data synchronization can occur between the two systems. 
  
  Tips & Tricks: 
  When setting up the External ID mapping, it is important to ensure that the fields are mapped correctly. This will ensure that data synchronization occurs correctly and efficiently. Additionally, it is important to ensure that all contacts have a unique External ID assigned to them, as this will prevent any duplicate contacts from being created in either system.
