Planned orders are generated for in-stock with production orders

Symptoms

Planned orders are generated even though you have items in stock and production orders already exist for them.

Resolution

You might be able to fix this issue by increasing the Positive days value for the relevant groups on the Coverage group page. This change will cause the system to determine whether on-hand inventory can be used for the demand. Then a new planned order won't be generated for the items that are in stock.
