I am clear of BAdI Definition and Implementation. Not sure of the place where to do the coding in the standard program. Will there be any points like user exits(or enhancements). Also I am clear of SMOD/CMOD concepts.
Prior to asking this question I did so much of research in this fourm. I could not able to find the corrrect answer.
May be I am compring this concept with user exits(or enhancements). Please give some light on this topic. Thanks in advance.
