The integration occurs through XML (eXtensible Markup Language) integration messages posted on the Connector Database by the legacy systems or MSCRM. Those messages can have two directions:
From ERP : integration messages posted by the legacy systems. Connector will read, validate, and insert them on MSCRM;
From CRM : integration messages posted by MSCRM. The creation of messages is obtained through Plugins or Workflows, and MSCRM will post those messages on Connector database.
Besides operating using Microsoft-supported methods and classes, Code-K Connector offers full possibility of entity and relationship insertion, i.e. accounts and its related contacts.
