About check po no in sales order type.

Question

Hi SD experts:
                             When creating sales order,i want to implement checking whether purchase order number exists,and giving the 
                    waring message.
                           But  In the Customizing of sales order type,it can only check with a error message or do not check.
                           In the std SD Customizing,how can it implement,pls give me some advice.
                                 Thank you very much.

Kindly check following SAP Notes:
Note 325894 - No message if purchase order number already exists
Symptom: If the 'Check purchase order number' flag is activated in an order type, when you change the sold-to party, the system does not issue a message that the purchase order number is already assigned for this customer.
Note 63056 - Validation of PO number for sales order
Symptom: If the preparations for consolidation are activated in profit center accounting, the partner profit center for a sales order can, if necessary, be determined from the respective purchase order.
To do this, the purchase order number entered in the sales order for the corresponding customer is validated.
If this number has less than 10 digits, you need to enter the number with leading zeros.
Note 317029 - Bad performance in the sales order due to PO number check
Symptom: Long waiting times occur within the order entry because the system carries out a check to determine whether a document with the particular order type already exists for the relevant sold-to party.
All the above are under category of Program error.
Hope it assists you.
Thanks & Regards
