INITIAL or NOT INITIAL

[Former Member]

Hi Everyone,

I have a situation here. The code goes like this.

In the below code, ZTEST-DECI is a Decimal type with length 11 and decimal 2.

PARAMETERS: p_deci TYPE ztest-deci.

IF p_deci IS INITIAL.

WRITE 'Empty'.

ELSE.

WRITE p_deci.

ENDIF.

Now if I leave P_deci in Input screen blank then it will print "Empty", and if I give the input as 0.00 it still prints "Empty".

I do not want that to happen. I want it to print 0.00 as output if I give input as 0.00 or 0.

Note: I do not want to change the Dala Element of ZTEST-DECI or declaration of p_DECI. However, I am ready for Type Casting.

Thanks in advance,

S.Dakshna Nagaratnam.

Hi,

IF p_deci IS INITIAL. is work only for data type Character.

thanks.

Hi

The comand INITIAL check if the value of a variable is INITIAL VALUE, the initial value depends on the data type of the of variable:

- for char variable is BLANK,

- for a decimal variable is ZERO,

- ...................................................

so if you insert 0,00, it means u insert 0, i.e the initial value: the behavior is correct.

What do you need to do?

Hi,

IF p_deci IS INITIAL. it works only for data type Character.

Hi,

Try defining your fields as below:

data : r_deci type p decimals 2.

and change you condition as initial as it is used to check character types.

Regds,

I see what we are trying to do here...

my requirement is just that,

if I give 0 in the selection screen output should be 0.00

if I do not give anything in the selection screen it should print as Blank.

My requirement is a little complex and the issue is because of this. Hence I cannot change the declaration.

Can someone help me with a Logic using type casting or something? -> Type P and Type C in Typecasting no luck.

Thanks and Regards,

Not possible without changing the data type or introducing a help field, I'm afraid. Wether you enter nothing or 0 or 0.00 on the selection screen, once PAI processing starts, the value of p_deci will be '0.00' internally.

Hi

Thomas is right, it can't do it: if you don't insert any value or if you insert 0: it'll be the same for the system, so u can't distinguish the two situation.
