abap -SHIFT

Former Member — Tue, 21 Mar 2006 22:00:08 GMT

hi folks,

I have small confusion with the use of SHIFT.

when do you use 'LEFT DELETING LEADING' and 'RIGHT DELETING TRAILING'

because I have a character variable

z1 = Operation# and I need to get rid of the '#'. I have declared z1 as char type.

I need to get it clarified once for all.

Thanks

Vinu.

Hi Vinu,

The best explanation is given in F1 help with example..

Shifts the contents of c to the left or right for as long as the string begins or ends with a character contained in c1.

If c does not begin or end with a character from c1, it remains unchanged.

Example

DATA: ALPHABET(15) VALUE ' ABCDEFGHIJ',

M1(4) VALUE 'ABCD',

M2(6) VALUE 'BJJCA '.

SHIFT ALPHABET LEFT DELETING LEADING M1.

The field ALPHABET remains unchanged.

SHIFT ALPHABET LEFT DELETING LEADING SPACE.

The field ALPHABET now has the following contents:

'ABCDEFGHIJ '.

SHIFT ALPHABET RIGHT DELETING TRAILING M2.

ALPHABET now has the following contents:

' ABCDEFGHI'.

myvariable = 'xxx123'.
SHIFT myvariable LEFT DELETING LEADING 'x'.
WRITE:/ myvariable.

The output in this case will be '123'.


myvariable = '123xxx'.
SHIFT myvariable RIGHT DELETING TRAILING 'x'.
WRITE:/ myvariable.

The output in this case will be

'   123'

Hi Vinu,

When you use SHIFT (LEFT/RIFGT) pl note that the left or right of the field is then padded with blanks. If you do not want the blanks, you are better off moving the field contents using offsets.

Is that really a '#' or is it some special character like tab that got uploaded from a file? When you upload a file that has special characters, you will see '#' in the contents, but when you try to remove it using any of the string operations you will not be able to do it.

Hi Vinu,

Please take a look at this link for sample code.

Hope this will help.

Hi Vinu,

DATA: TEXT(10) VALUE 'Operation#'.

SHIFT TEXT RIGHT DELETING TRAILING '#'.

write:/ TEXT.

Re: abap -SHIFT

Why not just use REPLACE:


DATA: z1(20) VALUE 'Operation#'.

REPLACE '#' WITH '' INTO z1.

Thanks but the syntax is not working in the program when I am trying to remove the trailing '#' sign.

ZAUS02 = itab_in-aus02 ( the value is Operation#)

and aus02 is CHAR(10) declared in the itab.

SHIFT ZAUS02 RIGHT DELETING TRAILING '#'.

After that I have to compare the value in ZAUS02 USING if CONDITION.

IF ZAUS02 = 'Operation'

I hope you got the point here.

Thanks

Vinu.

You would have to shift it back to the left removing leading spaces. Try using replace instead.

Infact I tried that but it did not work, so I came to this, It's so simple but what am I missing here?

Did you se the code I posted? You can just cut and paste it to see if it does what you want.

Srinivas, you are right, it comes from the external file in the .csv format, hecne I am not able to remove it.

But in a similar case in a different program I was able to remove the leading '##' signs using 'left DELETING leading' syntax for the value getting from the flat file.

why not here?

Thanks

Vinu

former_member186741 — Tue, 21 Mar 2006 22:58:54 GMT

why not change the if to:

IF ZAUS02(9) = 'Operation'.

Re: abap -SHIFT

Former Member — Tue, 21 Mar 2006 23:02:15 GMT

Then try:


DATA : code TYPE x VALUE '09'.
REPLACE code WITH '' INTO z1.

Folks, I got the issue.

Please help with the logic.

For the field 'ZAUS02' i AM READING THE VALUE from flat file the length of the field is CHAR10.

when the value is less than 10 it reads the value as with a trailing '#' like in 'Operation#'

Only in such case I need to get rid of the '#' sign and when the value of the field is equal to the size 10 no '#' sign is displayed.

then i go it works fine to check the IF condition..

Foe example:

ZAUS02 = Functional

it is fine

if ZAUS02 = 'Functional'

elseif ZAUS02 = 'Operation' (for this ZAUS02 needs to get rid of the # sign)

This is what I am trying to achieve here.

Thanks

Vinu

that's fine

Assuming the # is really a tab, the (second) code I posted should work. It did when i tested it. If it's not a tab, you'll have to find out the hex value of it.

I am sorry Rob, I did not understand the 'code' can you elaborate on it ?

Thanks.

Re: abap -SHIFT

Former Member — Tue, 21 Mar 2006 23:28:45 GMT

The variable CODE is a one byte hex field with the value X'09' (which I believe is the value of a tab). If you replace any instances of X'09' with a blank or null, it should get rid of it.

Do a F1 on DATA->Simple field definition->Addition 1 (type). It's discussed there.

Rob

Does this help:


DATA : tab TYPE x VALUE '09'.
REPLACE tab WITH '' INTO z1.

Sorry Rob, both did not work, I find it really strange, because for an earlier program I used the 'SHIFT' command to eliminate the leading '#' for the values and was able to upload.

That was a Numeric char variable and this is a char variable.

Thanks foryour help. Let me know if You have any leads to it, I shall continue working on it.

I shall ward the points and keep the thread open.

Vinu.
