I want to understand the difference between IDOC/ALE/BAPI/BADI in context to a functional consultant.what is the role of each with an EXAMPLE.I want to basically understand with examples w.r.t SD or MM instead of theory which i could get in forum.
What is the role of a functional SD consultant, in these technology mentioned?
If i have to Test a BAPI or BADI what is that i should test???what is the T codes to be tested ? How to go about it??
Like in case of Order to cash testing, i will check if the sales cycle runs well, using T codes, Va01, vl01n, vf01.
