The vendor may have created a new ingredient because it was missing from the list of available ingredients or may have chosen an ingredient from the dictionary. Newly created ingredients and ingredients selected from the dictionary have to be approved first, otherwise you will not be able to accept the form. You will be notified when you try to accept such a form:
To approve the new ingredient, proceed as follows:
The new ingredient is written in red in the Ingredients section, with the Accept button located next to it.
Click on Accept to accept the ingredient. The ingredient has been accepted and the text color changes.
Now you can go back to the Definition tab and accept the form.
If you do not want to accept the ingredient (e.g. there is a typing error in the name, the ingredient is on the list but the vendor just did not find it, etc.) and want the vendor to correct the error, you have to reject the form. Write a comment to tell the vendor how to correct the mistake.
