RSSH hierarchy maintain userexit IF_RSSH_HIERMAINTAIN

I need to add a button and the function in the standard class cl_rssh_maintain calling on BW.

Button should call my part of the program.

I created a program in which calling class:

call method cl_rssh_hiermaintain=>start

exporting

i_hieid = '02EL4FGSDQ8J9SBKE1H00HK7P' "my test hierarchy

i_objvers = 'A' "active version

• i_s_hiesel =

i_mode = 'M' "modify

• I_T_MDHIERATTR =

i_r_userexit = l_if_userexit "my interface user exit (problem) !!!

exceptions

cancelled = 1

others = 2

.

Works great, maintenance of the hierarchy is displayed without problems.

In basic program, I filled the class CL_GUI_TOOLBAR with no problem.

I added two more buttons and features. The test object is functioning well.

But I need send it to the class interface IF_RSSH_HIERMAINTAIN.

I used this code for fill interface, but is still empty:

try.

l_if_userexit->change_toolbar( exporting i_r_toolbar = go_toolbar ). "go_toolbar is filled CL_GUI_TOOLBAR

catch cx_sy_ref_is_initial into l_ref.

l_ref->get_text( receiving result = l_msg ).

endtry.

l_msg give me (Dereferencing of the NULL reference).

When I looking for another steps functionality of the program, it should be use as an interface userexit.

No information, no documentation.

But how do I send CL_GUI_TOOLBAR through the IF_RSSH_HIERMAINTAIN to CL_RSSH_HIERMAINTAIN?

Anyone dealt with something similar? Any simple code or some path to documentation?

Thanks
