E1 PO Approval Email (Sender)

Hi Expert ,

When I tested "Change Customer Credit Limit" the JDE system will fire me using sender email from [JDEMAIL] Rule3=PSFT_system@oracle.com.

If I made change Rule3 from PSFT_system@oracle.com to somethings like JDECenter@system.com ,then it will use sender as JDECenter@system.com.

BUT ,itwas not be the same ways when testing PO Approval ,the F4209 trigger use system function f(x) --> Send Message which is always set sender email as email set in WHO WHO

Internet address.

Is this function as designed ?Is there any workaround to replace PO Approval email sender email using center email like
