Compare Two Structures or Itab at Runtime

Question

Hi Experts;
I want to do compare two structures or itabs in my program at runtime.
I will give two structures or itab names and I want to get difference between two structures names or itabs.
I know Diff Screen of ABAP Debug . I want to make same process but only with FM or Class.
Are there any FMs or Classes working this way?
Best regards.

I created my interface success . But It give error at runtime. Error mesaage : 'Error during interprocess communication; Debugger will be closed . Message Number TPDA151'
DATA l_ref_diff TYPE REF TO CL_TPDA_DIFF_STRUC.
data : xyz  TYPE REF TO IF_TPDA_DIFF_SERVICE.
data : p_var1 type TPDA_VAR_NAME,
          p_var2 type TPDA_VAR_NAME,
          lv_x type TPDA_DIFF_ATTR.
data : l_it_value_diff TYPE TPDA_DIFF_VALUE_DIFF_IT,
          l_it_main_diff TYPE tpda_diff_main_diffs_it.
p_var1 = 'CLIENTDATA1'.
p_var2 = 'CLIENTDATA2'.
lv_x-maxhits = 100.
CREATE OBJECT l_ref_diff.
xyz ?= l_ref_diff.
xyz->init( ).
xyz->DIFF( EXPORTING p_var1 = p_var1
                     p_var2 = p_var2
                     p_diff_attr = lv_x
           CHANGING p_it_value_diff_it = l_it_value_diff
                    p_it_main_diff_it  = l_it_main_diff ).
