=== Variant Selection Errors

Sometimes a selection error happens at the <<variant_model.adoc#understanding-variant-selection,variant selection level>>.
Have a look at the <<variant_model.adoc#sec:variant-select-errors,dedicated section>> to understand these errors and how to resolve them.

Component selection rules can also consider component metadata when selecting a version.
