Adding Marketing Attribute to BP on creation

Hello,

I'm looking to add a specific martketing attribute ( exists already) to a BP when it is created. I have found a FM to add the attribute to the BP, but I am not sure if there is a BADI for BP where I can code in this FM.

Incidentally FM is CRM_MKTBP_ASSIGN_ATTRIBUT_TAB, I have tried the FM via the TEST function in SE37 and it woks fine, just need to know where to code it in when a BP is created.

Regards
Chan
