Comparing two structures

[Former Member]

Hi all,

Can anyone let me know how to compare two structures ie., wheather all fields(sequence/datatypes) of <Structure1> are same as <Structure2>..

Cheers,

Hi there,

if you are comparing in some report program in debugging mode, then in the new sap debugger, we have a functionality to compare structures.... you can use that. ....

otherwise, compare the data types of the fields of the structures. If the data types are same , then the structures are identical . Also the number of fields shopuld also be the same.

Do get back if you need further help...

best regards,

Just do,

IF S1 = S2.

Hi Rahul,

do below

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name       = wa_structure1
    CHANGING
      ct_fieldcat            = it_fieldcat1
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.


  CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name       = wa_structure1
    CHANGING
      ct_fieldcat            = it_fieldcat2
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.


if it_fieldcat1[] = it_fieldcat2[].
,...success message
endif.

it works

Hi,

Try the below code.

DATA: lo_obj TYPE REF TO CL_ABAP_STRUCTDESCR.
DATA: lt_comp1       TYPE cl_abap_structdescr=>component_table.
DATA: lt_comp2       TYPE cl_abap_structdescr=>component_table.

lo_obj  ?= cl_abap_structdescr=>describe_by_name( 'STRUC1_NAME' ).
lt_comp1 = lo_obj->get_components( ).

lo_obj  ?= cl_abap_structdescr=>describe_by_name( 'STRUC2_NAME' ).
lt_comp2 = lo_obj->get_components( ).

if lt_comp1 = lt_comp2.
endif.

Thanks for your answers, but I wanted to compare two structures of workareas(not values in it).

for ex: <WA1> = <WA2>...?
