Comparing 2 internal tables in UNICODE

Former Member — Fri, 17 Aug 2007 09:37:16 GMT

HI guys,

I have to compare 2 internal tables with same structure. Every field excepting first field should be compared.

Old, non unicode code is below.


DATA: a  TYPE TABLE OF pc20e WITH HEADER LINE,
           b  TYPE TABLE OF pc20e WITH HEADER LINE.

IF a+1 = b+1.
  WRITE: / 'Hello World'.
ENDIF.

That´s just an example of course. The real code is in a HR user exit, so i can´t deactivate UNICODE Check.

Thanks a lot.

data: flag(1) type c,

l_index type sy-index.

sort: a,b.

l_index =1.

loop at a from index l_index.

read table b index l_index.

if sy-subrc eq 0.

compare the common fields.

if mismatch.

flag =1.

exit.

endif.

else.

flag =1.

exit.

endif,

l_index =l_index+1.

endloop.

if flag eq 1.

write:............

endif.

Guess, that code doesn't´t resolve the problem.

I want to compare every row, so sy-index isn´t very helpful.

I want to ignore the first column !!

The problem is, that the first field of table is not character like.

Hello Alexander

I would copy the two internal tables into two temporay itabs of the same structure and initialize the values in the first itab field:

DATA:
  lt_itab_pbo   TYPE ...,
  lt_itab_pai    TYPE ...,
  ls_entry        LIKE LINE OF lt_itab_pbo.

  lt_Itab_pbo = itab1.
  lt_Itab_pai = itab2.

  CLEAR: ls_entry-field1.
  MODIFY lt_Itab_pbo FROM ls_entry
    TRANSPORTING field1
    WHERE ( field1 IS NOT INITIAL ).
  MODIFY lt_Itab_pai FROM ls_entry
    TRANSPORTING field1
    WHERE ( field1 IS NOT INITIAL ).

Next I would use the approach that I have published in:
