I have the following requirements from my customer, please give me detailed solution.
as you know, we use status profiles to approve sales orders, but it is now required to approve sales orders from an external system, the process might be:
1 create sales order in SAP via VA01, and sales order number will be saved
2 this sales order number and other fields such as sales area, customer, material, quantity etc sent to the external system thru an interface.
3 approvers in external system import or get a list of sales orders and perform the approval
4 the approval information sent back to SAP and udpate status in SO accordingly.
5 now sales order approved for further handling.
I think the process is something like the above, but I need to write a developing specifications at least feild mapping, I have no ideas how to do that.
Please help me out. thanks a lot
