Form to compare two fields ... cast needed?

[matteo_montalto]

Hi all gurus,

I'm rebuilding a report that performs a lot of checks by comparing fields of two different structures.

Basically, the check has a structure that is repeated over and over in many check: it looks like this:

IF srm_items-{field1} NE r3_services-{field2}.             
   t_temp-prezzi_errati = icon_red_light.
   t_temp-error_code    = '{errorcode}'.
   IF counter_s = 0.
      PERFORM add_son_in_t_temp USING srm_items e_backend w_obj-posting_date w_obj-changed_at.
   ELSE.
      PERFORM add_additional_error_temp USING srm_items 0.
   ENDIF.
   counter_s = counter_s + 1.
   fl_errore_s = 'X'.

I was thinking to create a form, say 'check_son', that takes as USING parameter , and . My doubt is about types ad casts; in a check, could be a text string, in another a number, in another again a guid, and so on. Always simple field (no structures or complex field by now), but for what that concerns my FORM:

FORM check_son USING compare1

compare2

errorcode.

how should I declare the form in order to have the check working? I mean, I'd like that compare1 and compare2 get the same TYPE of the parameter I pass.. Is there a way? Or implicitly the params are converted into text (this should not work for me)?

Thanks in advance

Hi Matteo,

If the parameters are not types then a cast may occur in the form itself.

It should be OK, but it depends on what you manage in the form...

Hope that helps.

Hi Laurent,

if I leave the params without types, the default is that they interpreted as text.

The problem is that I will compare fields that are typized differently, and I'm scared about the "implicit" conversion in text of the field value.

Suppose I have to make a comparizon between two numeric field:

srm_item-number_int , which has value 000000001

and

foo_item-numero, which has value 01.

If the comparison is made between numbers, everything's ok. If I pass these two params to the form declared as above, I think it's a ko...

I hope the situation it's a bit more clear now... Basically, I'd like to know if there's a way to pass a non typized parameter to a form and obtain in the form itself the correct typization.

Two solutions:

- replace the form by a macro

- implement a dynamic data declaration

Hi Dieu,

can you be more specific and address me to some example/documentation? I don't know macros and I don't know how to implement dynamic declaration in abap. Thank you.

Hi, Matteo

Test the following Sample Code it will help you to understand the working of Macros.

DEFINE check_son.
  if &1 NE &2. " If Field1 Not Equal Field2
    &3 = 'NE'. " In This Variable it will Return Error Code NE for Not Equal and EQ for Equal
  else.
    &3 = 'EQ'.
  endif.
END-OF-DEFINITION.
DEFINE write_message.
  if &1 = 'EQ'.
    write: 'Two Numbers are Equal', /.
  else.
    write: 'Two Numbers are Not Equal', /.
  endif.
END-OF-DEFINITION.

DATA: f1 TYPE i,
      f2 TYPE i,
      error_code(2).
f1 = 10. f2 = 15.
check_son f1 f2 error_code.
write_message error_code.
f1 = 10. f2 = 10.
check_son f1 f2 error_code.
write_message error_code.

Please Reply if any Confusion,

Best Regards,

Hi,

If there is some process in a program which is called frequently then we use macros. We can create a macro using the DEFINE u2026 END-OF-DEFINITION statement. Unlike function modules, macros are not available throughout the system and are available only in that particular program.

Example:

data : result type I.

define macro.
 result = 1 + 2.
 write result.
end-of-definition.

macro.

this macro can be called where ever necessary.

Thanks,

Sri.

In addition: in a macro you can use specific statements, such as "AT <fielld>... ENDAT", that you cannot use in a form.

Thanks a lot experts,

macros did the job perfectly
