RTTS is for ABAP Runtime Type Services (RTTS). it allows you to do many things dynamically at runtime. you can check class "cl_abap_structdescr" and also check the following link
RTTS is run time type services. Combination of RTTC and RTTI in a class hierarchy. The RTTS methods get information on data types and classes of objects, or create new data types in the form of type objects. The RTTSs are implemented as a hierarchy of type classes from which type objects can be created.
RTTC Run Time Type Creation - Creating data types during runtime of the program
The RTTS are implemented through a hierarchy of type classes that contain the methods for RTTC (Run Time Type Creation) and RTTI (Run Time Type Identification). With the help of these system classes it is possile
- To determine type information of existing instances and type names of the ABAP type system at runtime.
RTTS(Runtime Type Services) is used to define or create variables at dynamically.
RTTS is made of 2 components.
RTTC(Runtime Type Creation) is used to create new variables with any definitions. And we can create the variables by using abap statement 'CREATE DATA ..... TYPE DATA....'.
RTTI(Runtime Type Identification) is used to get the definition of existing variables or types.
We can call RTTI and RTTC by using methods in CL_ABAP_*DESCR classes.
