In Customizing for Distribution (ALE), you can define filter values for each receiving system and for the message type MATMAS. You do this in the activity Maintain Distribution Model. The system then filters the data records for the corresponding IDoc segments, distributing only those with the defined filter values.

The IDoc segments have a hierarchical structure. Due to these hierarchical dependencies, data for subordinate segments is also filtered automatically if data for the higher-level segment is filtered out.
