The Data PDU shall contain the following fields:

1. Simulation Management PDU Header - These fields shall identify the PDU header information, the originating entity, and the intended receiving entity. The Simulation Management PDU Header shall be represented by the Simulation Management PDU Header Record described in 5.3.29.
   
2. Request ID - This field shall identify the matching response to a Data Query PDU or Set Data PDU made by the simulation manager. This field shall be represented by a 32-bit unsigned integer.
