Transmission Medium - External send and Special Function
Can somebody explain me the difference between these 2 transmission mediums, External Send and Special Function. This is in the Output type config. (processing functions).
The logic behind is output type is just to create an entry in the NAST table, it has a very simple program logic (return_code=0).
What should I use in my case?, will either involve configuring a Communication Strategy?
Any help is appreciated.
Usually Special Function Output types are used if you are not using the standard outputs like IDOC, Print for which SAP standard programs and mehtods/Forms(SAP SCRIPTS) are available. If you want to create an output other than those or if you need some other functionality then you can maintain Special Function Output types and need to maintain the program to process that output type.
