How to Programmatically Create and Activate an ABAP Class

[shreevathsa_s]

Hi,

I have a requirement to programmatically create and activate an ABAP class that implements a 'pre-defined' interface.

Do you have any ideas how this can be done?

Thanks,

Hi,

Try if GENRATE SUBROUTINE POOL keyword can be of your help.

See the below example,

DATA itab  TYPE TABLE OF string. 
DATA prog  TYPE string. 
DATA class TYPE string. 

APPEND `program.`                     TO itab. 
APPEND `class main definition.`       TO itab. 
APPEND `  public section.`            TO itab. 
APPEND `    class-methods meth.`      TO itab. 
APPEND `endclass.`                    TO itab. 
APPEND `class main implementation.`   TO itab. 
APPEND `  method meth.`               TO itab. 
APPEND `    message 'Test' type 'I'.` TO itab. 
APPEND `  endmethod.`                 TO itab. 
APPEND `endclass.`                    TO itab. 

GENERATE SUBROUTINE POOL itab NAME prog. 

CONCATENATE `\PROGRAM=` prog `\CLASS=MAIN` INTO class. 

CALL METHOD (class)=>meth.
