It's very unusual in your company how to manage the inventory. Both you and white lady have certain quantity of inventory. If she doesn't have enough, she will get from you, which results in the shortage of your stock and you cannot meet customer's demand. Is that the issue? Please correct me if I misunderstand.

The issue is the accuracy of the forecast. The forecast for same product should be coordinated now matter who is the customer or who is the sales person. The forecast should be based on the history demand, customer purchsing order, seasonal effects, inventory carrying costs, production capacity, production lead time, transportation and the obsolete risk of product.

Most of time for the customers who place purchase order, the rule should be "first come and first serve" unless the customer is important and you make more porfit margin from this customer.

For each sales persons, of course they have the incentives to meet their customers ahead so that they can get more bonus and less complaints from their customers. But as a company, you need to have an overall picture.

As the suggestions per previous post, in order to solve this problem, first talk to this lady and ask the reason why she took your share, what consequence for you and how to resolve this issue in the future. Second, if you and she cannot resolve the issue, set up a meeting with her, your manager, and her manager to discuss. Before the meeting, collect the data (how many times, quanity, date, and the negative impact). Also, make suggestions how to resolve this issues. Please think about three options. Each option needs to have a cost and benefit analysis not only operationally but also financially. Please us the number if possible.
