Comparing 2 identicals structures.

Former Member — Wed, 05 May 2010 09:58:07 GMT

Hi,

I have to find the fields that are differrent in two big structures.

Rather than comparing all fileds one by one, i was wondering if there is quicker way to do it?

Or maybe a Function module?

Thanks for your help.

hello O ,

try something like this



type-pools: abap.

data: gt_comp1             type standard table of abap_componentdescr,
      gt_comp2             type standard table of abap_componentdescr,
      gs_comp              type abap_componentdescr,
      go_struct            type ref to cl_abap_structdescr.

go_struct ?= cl_abap_typedescr=>describe_by_name( 'BKPF' ).
gt_comp1 = go_struct->get_components( ).

go_struct ?= cl_abap_typedescr=>describe_by_name( 'BSEG' ).
gt_comp2 = go_struct->get_components( ).

if gt_comp1[] ne gt_comp2[].
  write: / 'Error'.
endif.

You can create a small custom program for this. You can get all the fields in the structure using FM DDIF_FIELDINFO_GET. Now, compare the both the internal tables and delete the duplicate entries using read inside loop.
