I just would like to know how to create user-defined functions. I tried to read some articles in the help.sap.com about this but I got confused with the features of the different functions available:
Simple Functions (Cache = Value)
Enhanced Functions (Cache = Context or Cache = Queue)
How is cache associated with the functions?
I've also tried to read the Advanced User-Defined Functions but it is more complicated there.
Is there a step on creating UDF? Also, what is the difference between Value, Context and Queue function options?
Thank you so much in advance for your help.
