Work Breakdown Structure or Internal Order Distribution 
Use
To carry out actual postings in distributed systems for internal orders and work breakdown structures, you can distribute the master data and status information of internal orders and work breakdown structures to more than one system.
Integration
Functions in the Master System
All functions for internal orders and work breakdown structures are available. However, in the master system you cannot call up the corresponding line items from line item reports if the line items all come from one receiving system.
You create the internal orders or the work breakdown structures in the master system. When you save them, the R/3 System distributes them automatically to one or more receiving systems. Through the filter objects Controlling area and order type or project profile, you control whether, and in which system, the internal orders or work breakdown structures are to be distributed.
You can also send released internal orders and work breakdown structures at a later date.
Functions in the Receiving System
Restrictions with Distributing Internal Orders and Work Breakdown Structures
f required, you can distribute the work breakdown structure first to the receiving system and then later on distribute the internal order.
The following business transactions are not possible in the receiving system:

If you set the deletion indicator in the master system for an internal order or a work breakdown structure and this change was adopted in the receiving system, the R/3 System also deletes the given internal order or work breakdown structure in the receiving system. To ensure that in the receiving system you cannot make postings to deleted objects, you should choose a time period corresponding to the setting of the deletion flag and the setting of the deletion indicator (for example, for internal orders by setting residence time 1). You must make sure that the Deletion flag status has been adopted in all receiving systems before you set the deletion indicator in the master system.
Data Flow
The data flow between distributed systems is identical for internal orders and work breakdown structures. This is described using the example of an internal order:
If you create or change internal order 10001 in system 1, it is automatically distributed to the receiving systems (in this case: system 2, system 3) and created or changed there using the same order number. System 1 is the master system of internal order 10001.
Prerequisites

Whenever possible, you should carry out all cross-system Customizing settings in one system.
or work breakdown structures: The project edit screens are defined identically in the master system and in the receiving systems. In the receiving systems you should include a lock indicator for the project edit screens, so that these project numbers cannot be used for new projects.
