Decimal data type multiplied by quantity data type

Question

Hi all,
i have a requirement where i have to multiply 3 fields, and get that result into fourth field.
example:
data: f1 type dec,    [Data type - Decimal; length 7]
        f2 type dec,    [Data type - Decimal; length 7]
        f3 type quan.  [Data type - Quantity; length 17]
data: f4 type ??
f4 = f1 * f2 * f3.
what will the data type of field f4?
Will field f4 be of decimal type. If yes, then what is the declaration syntax of f4.
can i declare it as:
data: f4 type dec.
When i do this, i get an error saying type DEC is unknown.
NOTE: For your information.I AM IMPLEMENTING THIS IN A  method inside a BADI.
Points will be rewarded.
Thanks in advance.

Hi
U need to use a reference to a dictionary field (like MSEG-MENGE) because there isn't an abap type to be used, the data type are only these:
C     Character     
N     Numeric string 
D     Date        (YYYYMMDD)
T     Time:            HHMMSS) 
X     Byte (hexadecimal)         
I      Integer                    
P     Packed number       
F     Floating point number
STRING  String         Variable empty string
If there isn't a dictionary field good for you, u can only use the type P.
So or:
DATA F4 TYPE MSEG-MENGE. (this field has 3 decimals)
or
DATA F4(16) TYPE P DECIMALS 2.
