To distribute Customizing data, filter objects for the CONDAT message type are entered in the distribution model. When you maintain the Customizing data distribution in the distribution model and then distribute the model:

• The Correction and Transport System distributes the customizing data from the maintenance system to the receiver systems specified in the distribution.
• The maintenance of customizing data objects is locked in the systems specified as the receivers of the customizing data objects. Only those customizing data objects to be distributed to a specific system are not affected.

When you maintain Customizing data, your changes will be recorded by the Correction and Transport System. A transport request is required for this. After you have maintained the Customizing data, the change request is released and is ready for transport.

When the transport request is released, the ALE distribution model is checked to ascertain whether other systems need to know about the changed customizing data objects. If so, Transaction BD77 is called with the parameter transport request and a list of all the objects is displayed. The transport request is then processed further in one of two ways:

1. A transport request is generated for each system, containing the exact set of objects that are defined by the intersection of the distribution model (message type CONDAT) and the request just released. This transport request must then be released and transported.
2. An IDoc for the message type CONDAT can be sent to each system, which then generates a work flow item in the target system. The person processing the work flow item can display a list of all these objects (the same as with Transaction BD77) and can start Transaction SM30 or SCUO to start the standard tables synchronization for each object. The synchronization must be carried out manually.

We recommended you choose the first option and to notify the administrator of option 2 so that he/she does not have to synchronize the tables manually.
