Understanding these services will help you identify where they can be used, and do so effectively."Microsoft Dynamics AX 2012 Services" is a hands-on guide that provides you with all the knowledge you will need to implement services with Microsoft Dynamics AX 2012. The step-by-step examples will walk you through many of the tasks that you need to perform frequently when creating and using services."Microsoft Dynamics AX 2012 Services" provides detailed and practical examples for creating and using services that will make it a resource you will consult many times during your implementationsThis book helps you to identify situations where services can be used for your implementations. By providing step-by-step instructions for many of the common tasks, you will gain practical know-how on to get the job done.Easy to follow instructions are provided for all types of services you will encounter.

Asynchronous communication

So far in this chapter we have focused on synchronous communication using the NetTcp adapter. The file system adapter and the MSMQ adapter work asynchronously and differently to synchronous adapters.

Asynchronous adapters use two tables to store messages:

  • AifGatewayQueue: The AifGatewayQueue table is used in asynchronous processing of both inbound and outbound messages. Inbound messages are stored in this table after they are retrieved by the gateway receive service. Outbound messages are stored in this table after they are processed by the outbound processing service.

  • AifOutboundProcessingQueue: The AifOutboundProcessingQueue table is used by the send service framework to store requests for outbound messages. These requests are then processed by the outbound processing service that stores a message in the AifGatewayQueue table.

The following flowchart displays the relationship between the tables and the classes that are used for asynchronous communication:
