You can use selection conditions to ensure that all the objects relevant to a variant are selected:

• Selection conditions determine which variants require a specific component or operation
• Selection conditions determine when it is mandatory to assign a value to a characteristic

You can allocate selection conditions to the following objects:

• Characteristics
• BOM items
• Operations in task lists
• Sub-operations
• Sequences of operations
• Production resources/tools (PRTs)

A selection condition is fulfilled if the condition in it is unambiguously true.
