Automatic Completion of the Structure 
Use
The system automatically carries out this function if you create a Baseline.
Prerequisites
You have flagged all materials and documents that are relevant for Configuration Management in the material master records and document info records accordingly.
See:
Indicating the relevant objects.In Customizing Configuration Management you have determined which BOM usages are scheduled for the current life cycle phase (work step Application control ® Define life cycle profile ® Life cycle phases ® Selected usages).
Features
From the controlled object and from the end node of the structure from the configuration folder, the system looks for other objects that are relevant for the current configuration of the product. For this reason, the system evaluates the following objects:
For materials in the structure that are flagged as relevant, the system looks for BOMs that are planned for the current life cycle phase and includes these in the structure.
If an object in a BOM item (such as the material master record of an important assembly) is also flagged as relevant then the system carries out the search for other BOMs from this object. This operation is repeated over numerous levels of a multi-level BOM.
For documents in the structure that are flagged as relevant, the system looks for document structures and likewise includes them in the structure.
If an object (such as material) is in the structure and is flagged as relevant then the system also includes the linked documents in the structure.
In this way, the system ensures that the structure that you created in the configuration folder is protected against mechanical changes. The system expands the structure with other objects, however, under no circumstances does it overwrite an object that you have manually copied into the structure.
