Hello there, DanOR.
The Inventory Valuation Summary shows the quantity on hand, value, and the average cost for each product. Inventory Valuation Detail report on the other hand gives you the transactions for each inventory item, and how they affect quantity on hand, value, and cost.
Let's ensure that you used the same report period for both reports to show the same amounts. Then, look into the quantity on hand and asset value if they're correctly posted. You'll want to open a new tab and pull up one report from there so you'll just have to switch tabs.

Let me know if you have other questions. Take care!
