Customizing ALE Outbound
Processing 
ALE can note the application object contained for every outbound IDoc. Example: for a material master IDoc, the ALE layer creates a link between the material number and the IDoc number. For this, Customizing steps are necessary; see reference below.
In ALE receiver determination, you can define the cases in which a receiver receives or does not receive an IDoc; you can do this for each receiver individually. Example: for the material master record, you can define that a receiver only receives materials of a certain material type.
You have to define
the distribution criteria - the 
Filter Objects, as
described below:
· Assigning the Object Type for the Outbound Link to the Message Type
· Assigning the Application Object Type for the Outbound Link to the Message Type
The ALE outbound processing functions are under ALE Development: To find them choose Tools ® IDoc Interface/ALE ® Development.
