Notifications - Template for Incident Long Text

Good Day All

Can anyone guide me on the following :

i want to configure my email notification so that when the notification Alert is raised and the email notification is sent to the recipient i want to include additional information in the body text of the email

i am aware that the badi BADI_BUILD_MESSAGE is define for this but im not sure if the information i want included can be perfmored with the badi

i am looking to include the specific error message per the IDOC as displayed in WE02 - highligted in green) (See pic1)

this message is a standard message with concacetanations of values stored in table EDIDS

Thank you
