Update of ADR6 and ADRT from nwbc in SAP MDG for BP after CR activation

[karthik_sub]

Hi Experts,

I am using the nwbc screen for creating the BP.

I have standard mail id field and explicit custom field like mail assistant .

When the user fills up the value in mail assistant, then i need to update the mail assistant value in the ADR6 and ADRT respectively with the consumer numbers.

Later , if people changes the value based on consumer id...it should update automatically in ADR6 and ADRT.

For this case, when the user activates the CR...can i fill up the value in custom handler class like below structure..

Or, is there any better way to update my field(mail assistant) in ADR6 and ADRT.

As of now, system updates only standard mail id in ADR6 under standard address like below for example.

But not the mail assistant value . Kindly suggest me the same .
