Convertion rule.

Former Member — Sat, 06 Oct 2007 12:12:00 GMT

Hi,

i hv doubt in this code lines.

data: k type i value 17,

n type c value 'a'.

move k to n.

*move n to k.

write k

write n

if i m using "move k to n". i m getting output 17 *, but if i use "move n to k"

i m getting runtimeerror.

could anybody tell me abt this conversion rules. and why i m getting * and runtime error.

points for sure:)

Thanks, Ajay.

Conversion table for source type C

Target Conversion

C The target field is filled from left to right. If it is too long, it is filled with blanks from the

right. If it is too short, the contents are truncated at the right-hand end.

D The character field should contain an 8-character date in the format YYYYMMDD .

F The contents of the source field must be a valid representation of a type F field as

described in Literals .

N Only the digits in the source field are copied. The field is right-justified and filled with

trailing zeros.

I or P

The source field must contain the representation of a decimal number, that is, a

sequence of digits with an optional sign and no more than one decimal point. The

source field can contain blanks. If the target field is too short, an overflow may occur.

This may cause the system to terminate the program.

T The character field should contain a 6-character time in HHMMSS format.

X Since the character field should contain a hexadecimal-character string, the only valid

characters are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. This character string is packed as a

hexadecimal number, transported left-justified, and padded with zeros or truncated on

the right.

Source Type Date

Conversion table for source type D

Target Conversion

C The date is transported left-justified without conversion.

D Transport without conversion.

F The date is converted into a packed number. The packed number is then converted

into a floating point number (see corresponding table).

N The date is converted into a character field. The character field is then converted into

a numeric text field (see corresponding table).

I or P

The date is converted to the number of days since 01.01.0001.

T Not supported. Results in an error message during the syntax check or in a runtime

error.

X The date is converted to the number of days since 01.01.0001 in hexadecimal format.

Source Type Floating Point Number

Conversion table for source type F

Target Conversion

C The floating point number is converted to the <mantissa>E<exponent> format and

transported to the character field. The value of the mantissa lies between 1 and 10

unless the number is zero. The exponent is always signed. If the target field is too

short, the mantissa is rounded. The length of the character field should be at least 6

bytes.

D The source field is converted into a packed number. The packed number is then

converted into a date field (see corresponding table).

F Transport without conversion.

N The source field is converted into a packed number. The packed number is then

converted into a numeric text field (see corresponding table).

I or P

The floating point number is converted to an integer or fixed point value and, if

necessary, rounded.

T The source field is converted into a packed number. The packed number is then

converted into a time field (see corresponding table).

X The source field is converted into a packed number. The packed number is then

converted into a hexadecimal number (see corresponding table).

Source Type Integer

Type I is always treated in the same way as type P without decimal places. Wherever type P is

mentioned, the same applies to type I fields.

Source Type Numeric Text

Conversion table for source type N

Target Conversion

C The numeric field is treated like a character field. Leading zeros are retained.

D The numeric field is converted into a character field. The character field is then

converted into a date field (see corresponding table).

F The numeric field is converted into a packed number. The packed number is then

converted into a floating point number (see corresponding table).

N The numeric field is transported right-justified and padded with zeros or truncated on

the left.

I and P

The numeric field is interpreted as a number, and transferred to the target field, where

it is right-justified, and adopts a plus sign. If the target field is too short, the program

may be terminated.

T The numeric field is converted into a character field. The character field is then

converted into a time field (see corresponding table).

X The numeric field is converted into a packed number. The packed number is then

converted into a hexadecimal number (see corresponding table).

Source Type Packed Number

If the program attribute Fixed point arithmetic is set, the system rounds type P fields according to

the number of decimal places or fills them out with zeros.

Conversion table for source type P

Target Conversion

C The packed field is transported right-justified to the character field, if required with a

decimal point. The first position is reserved for the sign. Leading zeros appear as

blanks. If the target field is too short, the sign is omitted for positive numbers. If this is

still not sufficient, the field is truncated on the left. ABAP indicates the truncation with

an asterisk (*). If you want the leading zeros to appear in the character field, use

UNPACK instead of MOVE.

D The packed field value represents the number of days since 01.01.0001 and is

converted to a date in YYYYMMDD format.

F The packed field is accepted and transported as a floating point number.

N The packed field is rounded if necessary, unpacked, and then transported rightjustified.

The sign is omitted. If required, the target field is padded with zeros on the

left.

I and P

The packed field is transported right-justified. If the target field is too short, an

overflow occurs.

T The packed field value represents the number of seconds since midnight and is

converted to a time in HHMMSS format.

X The packed field is rounded if necessary and then converted to a hexadecimal

number. Negative numbers are represented by the two's complement. If the target

field is too short, the number is truncated on the left.

Source Type Time

Conversion table for source type T

Target Conversion

C The source field is transported left-justified without conversion.

D Not supported. Results in an error message during the syntax check or in a runtime

error.

F The source field is converted into a packed number. The packed number is then

converted into a floating point number (see corresponding table).

N The date is converted into a character field. The character field is then converted into

a numeric text field (see corresponding table).

I and P

The date is converted to the number of seconds since midnight.

T Transport without conversion.

X The date is converted to the number of seconds since midnight in hexadecimal

format.

Source Type Hexadecimal

Conversion table for source type X

Target Conversion

C The value in the hexadecimal field is converted to a hexadecimal character string,

transported left-justified to the target field, and padded with zeros.

D The source field value represents the number of days since 01.01.0001 and is

converted to a date in YYYYMMDD format.

F The source field is converted into a packed number. The packed number is then

converted into a floating point number (see corresponding table).

N The source field is converted into a packed number. The packed number is then

converted into a numeric text field (see corresponding table).

I and P

The value of the source field is interpreted as a hexadecimal number. It is converted

to a packed decimal number and transported right-justified to the target field. If the

hexadecimal field is longer than 4 bytes, only the last four bytes are converted. If it is

too short, a runtime error may occur.

T The source field value represents the number of seconds since midnight and is

converted to a time in HHMMSS format.

X The value is transported left-justified and filled with X'00' on the right, if necessary.

data: k type i value 17,

n(3) type c value 'a'. --> try it like this.

move k to n.

*move n to k.

write k

write n.

it will work fine.

y your getting error menas.

1. u can move one integer variable to character but not to move character to integer.

2. y '*' sympol is comming na u didn't declare the length of the character.

3.if u specify the length of the character na u can move .

4. u can't get 17* . u should get only *. i think so..

5. type concersion error will be occur if u 'move character to integer'.

6. y u r getting menas the default character value is '',so u can't move '' to any integer value.

Thanks for thee reply..but why cant we move character to integer vartiable but can mone viaversa

Re: Convertion rule.

Former Member — Sat, 06 Oct 2007 12:32:35 GMT

u can move if u specify the legth of the character in character field.

ex.

data: k type i value 17,

n(2) type c. -->spcify the length of the character.

if we specify the lenght we can move integer to character but not char to int

Hi,

U can move TYPE c filds to TYPE i until the TYPE c variable( in ur case n)

contains a numerical value.

TYPE c- '23' -> i : YES.

TYPE c- 'r1' -> i : not possible ,gives runtimedump as 'r1' is not convertable to TYPE i.
