packed decimal allocated length

[Former Member]

hi

i saw multiple sap help docs but could not find out how the length of a packed decimal variable is allocated?

i mean if I declare

Data : abc type p length 16  decimals 2

will it allow 16 digits followed by a  decimal ( dot ) followed by 2 chars

xyz type p length 3 decimals 2

will it allow total 3 digits including decimal(dot ) and 2 decimal digits

please give a specific answer and not links as I have even debugged and seen that different lengths are allocated at diff times

thanks

Hi Hema,

Maximum suppoted length 31

Data : my_data type p type length 16 decimals 14.

it can hold '1234567890123456.12345678901234'.

Hi Yakub,

then why is this code working ?

DATA : gv_result TYPE p LENGTH 12 DECIMALS 4.

gv_result = '1234567890123456.4567'.

write: / gv_result.

Here even though i have specified 16 digits before the decimal instead of 12 it is working

[Former Member]

use

DATA : gv_result TYPE p LENGTH 8 DECIMALS 4.

It will give you dump...

Beyond 8 it is 16

Thanks yakub .

can you tell me how much length is allocated to numeric data type

for interger it is 10 i suppose

Hi Hema,

Well for each specfic internal data type you can check SAP Online documentation

here is what you need.

Hi ,

May I know the reason for this question ?

Are there specific customer requirement ?

regards.

Hi,

Take an example decimal value 123456.123

Here total no. of digits= 9

Formula: 2N - 1  = 9.

                 N = 5.

Here Length = 5 and Decimals = 3.

IF we get N value as 5.5 , then we will take Length as 6.

Hope this will help you in packed decimal.

Regards,

Anil.

Hi Hema,

Data Type P :

The valid length for packed numbers is between 1 and 16 bytes; two decimal places are packed into one byte, whereby the last byte only contains one place and the plus/minus sign; after the decimal separator, up to 14 decimal places are permitted. Depending on the field length len and the number of decimal places dec, the following applies for the value area: (-10^(2len -1) +1) / (10^(+dec)) to (+10^(2len -1) -1) /(10^(+dec)) in steps of 10^(-dec). Values in between this range are rounded off.
