Hi,

First you need to create a an object of the class like

CREATE OBJECT class_name

Now using that object you can call the method

CALL METHOD class_name->method_name

Hi Chandru,

i get an error that you cannot create the object outside the class .

Since the method GET_DOCUMENT_DATA is private i cannot call it outside the class.

Regards.

Try inheriting the class CL_CRM_DOCUMENTS_PLM.

Private methods can only be called from another method in the same class. As this class is delivered by SAP you can do nothing with this class.

Inherting works only for protected methods,not for private methods. private methods cannot be called in an inherited class.

The only thing is too copy the source code into an own class or do amdification on the SAP class.

Check if this private method is being used by some public method. If yes u can call the public method from ur abap code.

for Accessing a private Method of a class you have to Call it from a Public Method of the same class.

Private Methods are not accessible outside the class or even in the derived class. If you want to access the Private Method inside Derived Class you have to Change Its ATTRIBUTE to Protected which behaves like Private Outside Class but As Public Inside the derived Class.

Hope this will help.

dear it is not possible to call a private method directly,Instead what you can do is you calla public method of that class inside that public method you can call the private members of the class.

1. Declare a method in public section of the class

2. In the implementation of the public method , call the private method GET_DOCUMENT_DATA..

3. Call the public method from your report program.

Hii!

You cannot call the private method directly.

To call a private method,

You call a public method first,

and then from that method

call that private method.

hi check this example..

 Class C2 is created using CREATE PRIVATE option. That means, only the class itself and its friends can instantiate this class.

 Class C2 has a private method M2 and a private attribute , NUM. This means that these components can be accessed by class C2 itself and its friends.

 Now, C2 has granted friendship to class C1.

 So, methods of class C1 can access private components of C2 as well as can instantiate class C2.

report

REPORT YSUBDEL.

CLASS C1 DEFINITION DEFERRED.

CLASS C2 DEFINITION CREATE PRIVATE FRIENDS C1 .

PROTECTED SECTION.

DATA : NUM TYPE I VALUE 5.

ENDMETHOD.

CALL METHOD OREF2->M2.

ENDMETHOD.

Hi rawoof,

private methods can only be called from within the class. If you get an error like "cannot create the object outside the class" then the constructor is private, too. This is a technique frequently used in factory methods, in that case You should have a method like get_instance that will create the object and give you a refernece. If a method is declared private, it will usually not make sense to call it from outside. Check the wehere-used-refernce of the private method to find out how it is used in public method.
