Hi Mohan,
Can you tell me whether the planned order created for the material is transferred to ECC or not ? I ask this question because I can see in your screenshot that planned orders are also stuck in "Not in IM" error category.Ideally you have to first send the planned orders to ECC and when the new number range come to APO only then you should convert the PP/DS planned order to Production orders.
I hope you are following the same steps.
Thanks
