v_var = v_data1 - v_data2.

data: v_test type i value 10,

v_test1 type i value 4,

output type i .

output = v_test - v_test1 .

write:/ output.

hi,

Yes you can very well use that ...



data : p_var1 type i value '10',
     P_var2 type i value '2',
     p_out type i.

p_out = p_var1 - p_var2.

write : p_out.

Hi,

data: v_num type i value 12.

v_num = v_num - 3.

write:/ v_num.

Hi sandeep,

You can use the subtraction operator i.e ' - ' sign.

But while using it be careul to give spaces in between operator sign and the variables you want to subtraction i.e.

var1 = var3 - var4.

I hope this may solve ur queris.

You can go ahead with the above solutions.

Thanks,

Ya i was trying to write like

wa_output-duedate = wa_vendor-base - wa_vendor-terms.

here it is saying relational operator '-' is not supported

Are you doing it inside an if or other control structure?

Post your code, is probably a syntax error

Re: Relational Operator '-'.

Former Member — Tue, 13 May 2008 16:28:33 GMT

LOOP AT lt_vendor INTO wa_vendor.

wa_output-name1 = wa_vendor-name1.
wa_output-duedate = wa_vendor-zfbdt + wa_vendor-zterm.
IF ( wa_output-duedate - p_audat ) LE 30.
wa_output-days30 = 'X'.
ENDIF.

endloop.

here is the piece of code

Yes, that's the problem, you can't do that in abap.

Just put the value of


wa_output-duedate - p_audat

in another variable and compare that variable in the if

Re: Relational Operator '-'.

Former Member — Tue, 13 May 2008 16:32:29 GMT

hi this can be done like this also...

LOOP AT lt_vendor INTO wa_vendor.

v_diff = wa_output-duedate - p_audat .

wa_output-name1 = wa_vendor-name1.

wa_output-duedate = wa_vendor-zfbdt + wa_vendor-zterm.

IF v_diff LE 30.

wa_output-days30 = 'X'.

ENDIF.

endloop.

hi,

do this way ..

data : lv_differ type i.

LOOP AT lt_vendor INTO wa_vendor.

wa_output-name1 = wa_vendor-name1.

wa_output-duedate = wa_vendor-zfbdt + wa_vendor-zterm.

lv_differ = wa_output-duedate - p_audat.

IF lv_differ LE 30.

wa_output-days30 = 'X'.

ENDIF.

endloop.

Ok. i got it thanks for the solution.

but why it wont work the other way.?

Re: Relational Operator '-'.

Former Member — Tue, 13 May 2008 17:22:54 GMT

Can I write expression like

IF 30 GE delay LE 60.
wa_output-days60 = 'X'.
ENDIF.

Re: Relational Operator '-'.

Former Member — Tue, 13 May 2008 17:30:37 GMT

no, you need to join them using the operand AND.

but is way better to use


IF  delay between 30 and 60. 
wa_output-days60 = 'X'. 
ENDIF.

Re: Relational Operator '-'.

Former Member — Tue, 13 May 2008 17:31:13 GMT

yes.. but in this syntax


DATA: delay TYPE i.
IF delay BETWEEN 30 AND 60.
ENDIF.

Because the ABAP interpreter doesn't work like that.

Interestingly, if you write a static method, say DIFFERENCE, of a class, say my_class, that finds the difference, you can write something like:

IF my_class=>difference( i_val1 = wa_out-duedata i_val2 = p_audat) LE 30.

But it would be pretty pointless!
