Dependencies let you do the following:

• Describe the interdependencies between characteristics and characteristic values
• Control which components are selected from a bill of material (BOM) and which operations are selected from a task list
• Change the values of fields in BOM items and operations during configuration

You use a special syntax in the dependency editor to define dependencies.

The SAP System supports the following types of dependencies:

• Preconditions
• Selection conditions
• Actions (obsolete)
• Procedures
• Constraints

The differences between global and local dependencies are as follows:

• Global dependencies are created centrally and can be assigned to several objects.
• Local dependencies are created for one object and can only be used with this object.

You can use dependencies in the following components:

• Component CA – Classification System
• Component LO – Variant Configuration
