Hello,

In standard Odoo, the "Apply on Variants" functionality for BoM components has limitations when it comes to defining complex variant conditions such as Color = Red AND Size = Big on a single component line.

For specific variant combinations, common approaches are:

• Creating dedicated BoMs for the required variant combinations.
• Restructuring variant and BoM setup to better match manufacturing requirements.
• Implementing a small customization if strict AND-based logic is required across multiple attributes.

The Product Configurator can assist with variant selection during sales, but it does not natively provide advanced AND-condition logic for Manufacturing BoM component applicability.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.

Hello,

In standard Odoo, the “Apply on Variants” field on BoM component lines is not really meant to work as an advanced AND-condition rule builder.

If you select multiple variant values on one component line, Odoo may treat them broadly, so it can behave like OR logic instead of strict logic such as:

Color = Red AND Size = Big

For this requirement, the usual approaches are:

1. Create a BoM for the specific product variant

   Example: one BoM specifically for “Red / Big”, where Component A is included.

2. Split the structure into more specific BoMs or subassemblies

   This is useful if only some combinations require different components.

3. Use custom development

   If you need dynamic AND logic on component lines, then a custom module is usually required to change the BoM explosion/component selection logic.

The Product Configurator is mainly for sales/product selection. It does not normally change the core BoM component matching logic in Manufacturing to provide AND conditions for “Apply on Variants”.

So if the number of combinations is manageable, I would recommend using variant-specific BoMs. If you have many combinations and need rule-based component selection, then a custom module would be the better long-term solution.
