Wrong contact person email used in sale order output

Hello,

We develop the following solution:

In sale order, we can send the output order confirmation by mail. In the customer data, we saved the email address (SZA5_D0700-SMTP_ADDR) and we added the partner CP in the partner function.

From the sale order, we can send our output by mail but the email used address is wrongu2026

But when we create a sale order, in the partner view, the email address displayed is not SZA5_D0700-SMTP_ADDR but SZA1_D0100-SMTP_ADDR (email from the business view).

How can we display the email address SZA5_D0700-SMTP_ADDR in the sale order ?

Thanks

Regards

Pierre
