Mail Subject based on Payload

Hi Gurus,

I want generate two emails one for Failed Records and one for Success Records using a value in the tareget field.

I have only one Target message but subect has to be changed based on value in the status field of target structure.

if Status value 'S' then the subject is SUCCESS Records and if status is E then subject is ERROR Records.

Can I get that value to my eMail Subject based on Payload?

Regards,

Sreeni.
