Potential Causes:
* Component Checkbox: Products marked as Components are typically excluded from being directly selectable in the Product Selection screen unless part of a bundle .
* Search Filter: Custom Search Filters on the Add Products button limit the display of products based on criteria such as product attributes or field values.
Excluded Reasons:
* Hidden Checkbox: This is generally used to hide products from the Quote Line Editor, not the Product Selection screen.
* Custom Action Condition: While these can limit the Add Products button's visibility, they do not directly affect individual product visibility.
Salesforce CPQ Reference Points:
* Documentation on Product Selection Behavior and Search Filters confirms these behaviors .
