Structural limits that apply to solution configurations, including hierarchy depth, total configuration count, and field mapping constraints.

Table 1. Solution configuration limits

Limit	Value and notes
Maximum hierarchy depth	4 levels, including the solution root. The BOM hierarchy can have an arbitrary depth.
Maximum configurations per session	20 total — the solution root plus up to 19 active child configurations across all depths.
Circular references	Not permitted. A blueprint cannot appear more than once in any path from a child configuration back to the solution root.
Configurable products per action	One configurable product per configurable product action. To add multiple child configurations from a single rule, add multiple configurable product actions to that rule.
Field mapping direction	Parent to child only, one level at a time. To continue a mapping across multiple levels, define the mapping on each blueprint in the chain.
Field types supported for mapping	Number, Text, Boolean, and Picklist only. For the full list, see Define field mappings for a solution configuration .
Sets and Product Pickers in mapping	Mapping of an entire Set or an entire Product Picker is not supported. Fields inside a Set can be mapped. Product Picker subfields cannot be mapped.
Reverting a configurable product action	Once a product action is marked as configurable, it cannot be changed back to a standard product action.
