Hi Mehdi,
Once order status is PCNF you cannot create lot with inspection type as 03. You need to reverse all the confirmations/Goods issue and activate 03 inspection type in material master, maintain MIC related data in routing and do Read Master data. Then system will create inspection lot.
For 03 inspection type manually inspection lot cannot be created. Once order is released inspection lot will be automatically created by system.
Thanks & Regards,
