Associating a Data Object to an RMM 
To allow mass creation of devices, you associate a receiver generation data object to a Receiver Meta Model (RMM) by mapping the data object node attributes with the attributes of the RMM.
Procedure
Log on to the Data Orchestration Engine (DOE) and start transaction SDOE_WB.
Choose Receiver Meta Model from the drop-down list.
Search for the RMM you want to which you want to associate a data object to.
Select the RMM from the search results.

In addition, you can choose F4 to select the data object from the list.
DO Category
Indicates the category of the data object
By default, REG category is specified which indicates that the data object belongs to the receiver generation category.
You can associate only the data objects that belong to the Receiver Generation category.
In the Single Value Attributes field, enter the required data object attributes corresponding to the RMM attributes.
In the Multi Value Attributes field, enter the required data object attributes corresponding to the RMM attributes.
Save the entries.
Choose Save from the standard toolbar.
You have associated a Receiver Generation data object to the RMM. When the initial load is triggered from the back-end system, the required flow services are called to create, update, or delete devices in bulk based on the values extracted by the Receiver Generation data object from the back-end system.
