When is it not necessary to build a new market supply schedule?

I believe the answer is: When there is a change in price

When there is a change in price, we need to re-arrange the quantity of our supply in order to make sure that we do not overstock.
Because the demand on the market became uncertain because of the price changing, building a market supply schedule during price change would be too risky.
