MRP run proposal only covers first requirement

Hello there gurús,

Im having an issue running MRP where the proposal only covers the requirement for the first PR for stock transfer order.

I have 4 PR for transfer stock from the plant where Im running MRP and the proposal should cover all this PR.

Also, I need to set a lot size procedure similar to EOQ calculation. I went for WI lot size procedure, but I'm not sure how is calculating the lot size. Delivery dates and quantities are in the screenshot.

Storage costs in %: 20 %

Ordering costs: 15

Thank you in advance!
