This article introduces the knowledge of "what is ABAP CCDEF". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

After we create a new ABAP class, we finish the code, and when we activate it for the first time, we will see that these start with the name of the class, followed by a large = symbol, and objects ending in five characters appear in the list to be activated. What the heck are they?

Let's do some research. Jerry in the 2019 year of the Pig New Year's Eve wrote articles SAP GUI and Windows registry once mentioned the registry of the Windows system, and ABAP Netweaver also has its own registry: TADIR and TRDIR. Objects created in either the SE80 or the SE11 transaction code will leave some marks in both tables.

Create the simplest ABAP class, one for each of the public,protected and private methods and properties, and the sparrow is small and well-equipped.

After activation, query the class name ZCL_ABAP_CLASS in the registry TRDIR and get the following record:

Thus it can be seen that the Class in ABAP is technically made up of several ABAP include programs that can be opened directly through SE38:

For the records in the above TRDIR, we can open them one by one with SE38 to figure out what they mean.

CCAU

The meaning of this AU can be used to help remember with ABAP Unit.

After SE38 opens the include program, it automatically enters the following interface and finds that the CCAU program stores the unit test code for this class.

CCDEF

DEF stands for Definition (definition). Open ZCL_ABAP_CLASS=CCDEF in SE38 and see this interface:

What is maintained here is the local definition of the ABAP class, including the local class, local interface, local type definition, and so on.

You can also enter SE24 first, and then click Local Definitions/Implementations to open it.

CCIMP

IMP stands for implementation (implementation). SE38 opens ZCL_ABAP_CLASS=CCIMP and you can see the implementation of the partial class.

CI

The private area definition of the class.

CO

The protected region definition of the class.

CU

The public domain definition of the class.

CMXXX

CM stands for Class Method,XXX is the method serial number of the class, based on hexadecimal, incremented from 1, for example, CM001 stores the implementation code of the first method of the class, CM002 represents the second method, and so on.

For example, when you open ZCL_ABAP_CLASS=CM001 in SE38, you see the source code of the first private method:

ZCL_ABAP_CLASS=CM002:

ZCL_ABAP_CLASS=CM003:

CCMAC

MAC is an abbreviation for Macro (macro), which stores the macro definition of a class.

How do you get these different ABAP include program names for a class in code?

Use the ABAP utility class CL_OO_CLASSNAME_SERVICE:

For example, if I want to know the include names of all methods in the CL_CRM_BOL_CORE class, make a breakpoint in the GET_ALL_METHOD_INCLUDES of the utility class.

Then open CL_CRM_BOL_CORE in SE24 and click Source Code Based:

The breakpoint is triggered immediately, and you can see from the call stack that in order to display the complete code of the ABAP class in Source Code mode, the code scattered in each include program needs to be read.

The correspondence between a class method and its include program name is clear at a glance.

In ABAP Type Group SEOP, the constant definition of the include type that starts with CC is stored in this article.
