Compare Two Structures or Itab at Runtime

[former_member212713]

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.

          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.

                     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 ).
