If I understood you correctly, you are creating a sales order from iStore. And you would like to generate an internal requisition to fulfill the sales order.
You need either an MRP/ASCP plan and a sourcing rule.
You need to run min-max on that item with appropriate sourcing setups.
Hope this helps
Thank you for your answer. In fact, yes I'd like to generate an internal requisition because what is ordered by the client is something produced in the company.
But the organization which receives the sales order from istore is not the one which will supply the items. So it has to create an internal requisition to the right organization.
So, if I use min/max and sourcing for these items, I have to declare the organization which produces the item as a supplier in the sourcing setup ?
Yes - you can setup min-max with sourcing details either on the org level item record or in min-max setup.
That will create an internal requisition.
Make sure you run the min-max with proper demand cutoff parameters.
