Difference between ALE / EDI
I have a question from long time. What is the difference between ALE & EDI.When I ask my friends They say in simple way. SAP - SAP (ALE) . SAP - NON SAP (EDI).
Today I read in a book .ALE/IDOC method can be used to connect to SAP - NON SAP (LEGACY). Now I am more confussed .
If any one can explain me the real difference I really appreciate the time.
