Relational Operator '-'.

[Former Member]

Hi

can anybody tell me if i want to subtract one thing from another(subtracting) how can I write the code?

can I use minus symbol for subtractions.

[Former Member]

v_var = v_data1 - v_data2.

[Former Member]

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.

Hi,

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

[Former Member]

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

Post your code, is probably a syntax error

[Former Member]

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

[Former Member]

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

[Former Member]

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.

Ok. i got it thanks for the solution.

but why it wont work the other way.?

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!

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.

[Former Member]

Can I write expression like

• IF 30 GE delay LE 60.

• wa_output-days60 = 'X'.

• ENDIF.

[Former Member]

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. 

[Former Member]

yes.. but in this syntax

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