Forecast Quantity is not completly been planned in the supply planning in fusion

Summary:

Hello All, We have uploaded 3 forecast for the 3 different dates while the supply plan is for around 150 weeks (more than 2 years) now when we check the forecast planned orders in the supplies and Demand Table, the planning engine is only providing the the partial quantity which is quite strange. Also, there is no further demand and no on-hand is available for the item so as per the expectation the complete forecast quantity should be planned from the supply planning. Please find the below screenshot for your kind reference.
