STO from Special Stock E

Hi all,

We are configuring a new process of MTO and the description is detailed below:

- Material 100001 is produced in Plant 1000.

- Plant 2000 sells the materia. So the Sales Order is created with Plant 2000.

- After that this material is produced in Plant 1000 and the requirement is transfer the material to Plant 2000 to do the expedition process.

However, the ATP does not confirm the stock whereas the stock is already assigned to an sales order.

Do you know if exist some way to use STO from special stock E (sales order)?

Thanks
