In Stock / Storage charges, click on Receival charges and get a screen looking like below.
click on the Type name matching your provider or the “Add a receival type” button at the top left and key as below.
The receival charge used will be the most specific. If you were to key nothing but the price into the below screen then it will catch everything. If you then added a “Valid from” date and “WHEAT” then any Wheat from that date will have e.g. $10 receival vs the catch-all value of $10.45.
