This table function declares two input parameters clnt (with the predefined value: #CLIENT) and carrid, and a list of elements that provide the return values of the AMDP method that implements the table function. They cannot be called as functional methods in ABAP, while AMDP-procedures can be called as ABAP methods. The client handling of an AMDP method that does not implement a CDS table function is defined by the usage of the respective AMDP Mar 16, 2024 · This document discusses implementing string functions in ABAP CDS views using CDS table functions and AMDP functions.
