Configure Product and Content Locking
Define the time (in minutes) for when products or content are locked while editing. During this time, other users can't edit the product record or content asset. The lock (applied before product editing) is released after this time.
If you lock a base product, Business Manager automatically locks the related variation products, unless locked by another user. This technique reduces the number of clicks you must make when editing a variation. When you unlock a base product, its variation products are also unlocked, unless locked by another user.
