I'd like to know how can I calculate formulation cost?
I can't add manually USD/100g values on Formulation tab of a Formulation Spec.
I also tried to create a USD/100g extended attribute on Material Spec, but a I can't see this value on Formulation tab of a Formulation Spec.
You should be able to override cost values on the formulation and process tabs. However, cost overrides are considered a design tool, so the formulation specification has to be in a workflow status with the "designable" tag for this feature to be enabled.
Ingredient costs can also be automatically pulled into the formulation specification using our cost library feature.
