Get a reference of a local class at another program

Hello experts! Sorry if this has been asked before, but I couldn't find exactly what I'm searching for.

Within function-pool MIGO (main program of transaction MIGO), there's a local class LCL_MIGO_KERNEL. This class has the private attribute PT_CHANGE_TAKEIT (which is an internal table).

During the execution of MIGO, for a certain criteria, I would like to clear the contents of PT_CHANGE_TAKEIT. Since it's a private attibute, I have managed to create a new public method that just clears it. This method was defined and inplemented within ENHANCEMENT SPOTS available all over SAPLMIGO. My method is ZZ_CLEAR_PT_CHANGE_TAKEIT. So far so good.

Now, I have to call this method. I have found no other ENHANCEMENT SPOTS in SAPLMIGO at a place where I would me able to make the call (eg, don't know if the criteria fits yet).

Inside BADI MB_MIGO_BADI, method LINE_MODIFY, I have just what I need to know if I should clear PT_CHANGE_TAKEIT.

However, inside here I don't have access to the instance of class LCL_MIGO_KERNEL (the instance itself is (SAPLMIGO)LCL_MIGO_GLOBALS=>KERNEL)

So far I have managed to get a pointer to the instance with:

  FIELD-SYMBOLS: <lfs_kernel> TYPE ANY.

    TO <lfs_kernel>.

So I have the instance of the class, but how can I call my method ZZ_CLEAR_PT_CHANGE_TAKEIT?

The command call method <lfs_kernel>->zz_clear_pt_change_takeit.

can't be done because ""<LFS_KERNEL>" is not a reference variable" as the sintax check tells me.

I have tried stuff like


  ASSIGN dref->* TO <ref>.

but nothing works so far.

I know if LCL_MIGO_KERNEL was a class from SE24 (not a local one), I could just create a field-symbol of that type instead of type ANY and it would work.

Does anyone have an idea how that can be done?

Thank you very much!

    I have managed to do what I needed by calling my method from other ENHANCEMENT SPOTS within SAPLMIGO and some extra coding on MB_MIGO_BADI, but unfortunately I couldn't do what I originaly wanted which was to call a method of a local class from another program, something that could be handy in other situations.

    If it's not lack of knowledge by myself and it really can't be done, I think the ABAP OO framework fell just short of having that flexibility, since I can get the field-symbol to point to the instance of the class, but just can't call the method because of syntax issues.

    My reply was duplicated (I'm sure I clicked Post message only once). It seems that SDN is having some issues with the Security Certificate.
