Hi Som
It´s really difficult to say that consumption should match in ECC and APO as there are multiple factors require to consider. As you are simulation version in case delivery of sales order is happening it would be readjusting the consumption in ECC where APO it will not ? You could also different consumption configuration with both the systems so I would say it´s not ideal comparison.
ECC is live system and surely there could be multiple things happening where in simulation version you might be having old picture so don´t compare them and I am sure it will never match 100%.
Please request you to close the thread following How to close a discussion and why process.
Thanks
