When i run MD4C report for sales order and item (whose delivery date is 23.04.2021), it throws error Error determining planning periods for planning calendar.
For same material having sales order delivery date as 20.11.2021, it does not throw the error. Planning horizon is 360days but this should not affect since for other sales orders, we are not facing this issue.
Also in MRP2, planning calendar is blank. Please help us to resolve the issue.
