Real-time ERP data access
The live link concept allows the apps to consume remote data in real time. In general the live link stands for making a remote API calls. The specific here is that the developer may use a simple API to make remote calls which allows then to the system administrator to actually route the call to any of the supported remote systems without a need to change the source code. This allows the apps to be able to communicate with different systems like Dynamics 365 Business Central, Dynamics 365 FO and others by only changing configurations on the backend side.
