Reg: DATASET of fixed length

I want my dataset to consist of 128 byte fixed length records, with spaces padding out the record length to 128 bytes
Can u help me how to code in ABAP programming or IS THERE ANY UNIX command for the same?

Hi sreenivas,
On the unix front , you can try 'awk' and 'sed' for formatting your input/output.
Check man pages for the above mentioned command.

Upload a Fixed Length file in terms of Bytes..

Hi,
Here is my query.
I have a fixed length file that I need to upload into my program from my presentation server.
The file is in a Shift-JIS Format.
The file is a fixed length format. But it is fixed interms of the number of bytes that each column occupies.
Eg. The 1st column takes 8 bytes, the second 15 bytes, so on and so forth. We do not know the no. of characters each column takes... just the numbe of bytes.
This is how I had approached the upload.
I created an internal table with just one field of type XSTRING.
I used GUI_UPLOAD FM with CODEPAGE = `8000`.
But i noticed during debugging that in each record, the moment a SPACE occured in the input file, it would stop reading and go to the next record in the file. Meaning, I loose all the data after the first occurance of SPACE.
Am I missing something here?? Why does the FM truncate after the first SPACE. ??
Do I need to declare the internal table in any other format..??

Creating a Fixed Length File

Greetings,
I'm creating an application that need to create a fixed length file on a UNIX system and need help. I have an internal table(s) which contain structures with fields of different lengths (type c) and so I have a routine that concatenates these fields into a single record to be sent to a file using the open dataset. This process is squeezing out all my spaces and so my fixed length file is lost. Can someone assist in creating a fixed length file from an internal table without using delimiters?
Thanks!

Uploading data into a fixed length file

hello experts,
I got a task to upload data into a fixed length positional file from internal table.So please help me.
regards,
sriram.

Hi there. What you basically need to do is set up the path and name for the export file, move your records to an output table, and then transfer the data to the file that you have specified. We usually set up our export programs so that the user can choose to download the file locally or onto the application server. So first we define the following fields on the selection screen:
PARAMETERS: p_file(128) LOWER CASE OBLIGATORY. "File
*path name from system standard
PARAMETERS: p_path LIKE rlgrap-filename MODIF ID fpn. "Path Name
PARAMETERS: p_local AS CHECKBOX. "Local File Flag
Then we use this to set the path to the application server:
INITIALIZATION.
CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
      logical_filename = 'Z_AO_HR_UP_LOAD'
      parameter_1      = space
    IMPORTING
      emergency_flag   = lw_emergency_flag
      file_name        = p_path
    EXCEPTIONS
      file_not_found   = 1
      OTHERS           = 2.
AT SELECTION-SCREEN OUTPUT.
make path name display only
LOOP AT SCREEN.
    CHECK screen-group1 = 'FPN'.
    screen-input = 0.                  "Output (Display) only
    MODIFY SCREEN.
ENDLOOP.
After your START-OF-SELECTION statement, you need to open the file for output:
IF p_local NE ztc_on.
Get Path/file Name using logical filename.
      CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
      logical_filename = 'Z_AO_HR_UP_LOAD'
      parameter_1      = p_file
    IMPORTING
      emergency_flag   = lw_emergency_flag
      file_name        = p_path
    EXCEPTIONS
      file_not_found   = 1
      OTHERS           = 2.
    IF sy-subrc <> 0.
      w_message = 'No Output file - Missing Logical File Z_AO_HR_UP_LOAD'.
      WRITE: / w_message.
      IF sy-batch = 'X'.               "Is this in a job?
        NEW-PAGE.
        PERFORM end_of_selection.
        MESSAGE e000(38) WITH w_message. "This causes the job to cancel
      ELSE.
        MESSAGE i000(38) WITH w_message.
      ENDIF.
      w_stop = 'X'.
      STOP.
    ENDIF.
*Check if output file is already present.
    OPEN DATASET p_path FOR INPUT IN TEXT MODE.
    IF sy-subrc EQ 0.
      CLOSE DATASET p_path.
      WRITE: 'Output Data file already present ', p_path.
*Use the following for logging error message
      CONCATENATE 'Ouput Data file already present ' p_path INTO
                   w_message.
      IF sy-batch = ztc_on.            "Is this in a job?
        NEW-PAGE.
        PERFORM end_of_selection.
        MESSAGE e000(38) WITH w_message. "This causes the job to cancel
      ELSE.
        MESSAGE i000(38) WITH w_message.
      ENDIF.
      w_stop = 'X'.
      STOP.
    ENDIF.
    OPEN DATASET p_path FOR OUTPUT IN TEXT MODE.
    IF sy-subrc <> 0.
      WRITE: 'Unable to open output dataset - ', p_path.
*Use the following for logging error message
      CONCATENATE 'Unable to open output dataset - ' p_path INTO
                   w_message.
      IF sy-batch = ztc_on.            "Is this in a job?
        NEW-PAGE.
        PERFORM end_of_selection.
        MESSAGE e000(38) WITH w_message. "This causes the job to cancel
      ELSE.
        MESSAGE i000(38) WITH w_message.
      ENDIF.
      w_stop = 'X'.
      STOP.
    ENDIF.
ENDIF.
Next you perform all of the steps to put your data in the internal table. After the end of selection we then transfer the data from the original internal table (which has many separate fields defined) to a second internal table, t_outfile, in which each record has a single field that is the total length of the original itab record:
*Internal table for Output data
DATA : BEGIN OF t_outfile OCCURS 0,
         text(1000).
DATA : END OF t_outfile.
Then you can download your file, checking whether it goes to a local drive or the application server:
IF p_local EQ ztc_on.
      CALL FUNCTION 'WS_DOWNLOAD'
    EXPORTING
      filename                = p_file
    TABLES
      data_tab                = t_outfile
    EXCEPTIONS
      file_open_error         = 1
      file_write_error        = 2
      invalid_filesize        = 3
      invalid_table_width     = 4
      invalid_type            = 5
      no_batch                = 6
      unknown_error           = 7
      gui_refuse_filetransfer = 8
      OTHERS                  = 9.
ELSE.
    LOOP AT t_outfile.
      TRANSFER t_outfile TO p_path.
    ENDLOOP.
ENDIF.
Now close your dataset if it is on the application server:
IF p_local NE ztc_on.
      CLOSE DATASET p_path.
    ENDIF.
I hope this helps!

Export Data To Fixed Length File

Hello,
I have a requirement to export a couple of files that need to be in a fixed length format.
I've tried opening the dataset and writing the records passing the column that the records should appear:
    WRITE /, field1, 10 field2, etc...
I've also tried to do it through SAP_CONVERT_TO_CSV_FORMAT and the text version as well.
Is there a predefined function that will allow me to export as fixed length?
Thank you in advance

Hi Jeff,
Following is the code to do the same:
DATA: file TYPE string VALUE `flights.dat`,
      wa   TYPE spfli.
FIELD-SYMBOLS TYPE x.
OPEN DATASET file FOR OUTPUT IN BINARY MODE.
SELECT *
       FROM spfli
       INTO wa.
ASSIGN wa TO CASTING.
TRANSFER TO file.
* TRANSFER LENGTH 200 to file.
ENDSELECT.
CLOSE DATASET file.
Best regards,
Prashant

Option to read fixed-length format, EXCEL or ASCII TAB delimited

Hi Experts,
I have a requirement for giving an option to read fixed-length format, EXCEL or ASCII TAB delimited in the selection screen.Kindly help me how can i read the fixed length format?
Thanks,
Ankita

As far as I could have understood your problem
You have to read the file with
Open dataset 'file path+name' FOR INPUT in text mode encoding default.
and move its contents to string type variable
Transfer to 'file path+name' to v_string.
Now as per your requirements you need to use Offsets to transfer the data into a work area.
For example
wa_task-year= v_string(4).
wa_task-month= v_string+4(2).
Please confirm if this is your requirement.

Need to download a file which si space delimted and has fixed length char

Hi,
I have a custom report which downloads an output file in text format.I need the contents to be space delimited.My file data contains numbers as well as characters.I ahve pased the parameter WRITE_FIELD_SEPARATOR = ' ' in the FM.Hwoever the space is introduced only oif the column value is a character.If its a number/digit,the columns are not seperated by space.
Now my data appears like that:
0000101310179.28 +0827200808 DHLBSRF VISA AUG 2008US021SW111 RYAN,BICOVNY
I want my data to be like this :
0000101310 179.28 + 0827200808 DHLBSRF VISA AUG 2008 US02 1SW111 RYAN,BICOVNY
DO I need to pass any additinal parametre?Also for fixed length characrets,do i need to pack/unpack data before passing to the FM ?
Thanks.

Loading "fixed length" text files in UTF8 with SQL*Loader

Hi!
We have a lot of files, we load with SQL*Loader into our database. All Datafiles have fixed length columns, so we use POSITION(pos1, pos2) in the ctl-file. Till now the files were in WE8ISO8859P1 and everything was fine.
Now the source-system generating the files changes to unicode and the files are in UTF8!
The SQL-Loader docu says "The start and end arguments to the POSITION parameter are interpreted in bytes, even if character-length semantics are in use in a datafile....."
As I see this now, there is no way to say "column A starts at "CHARACTER Position pos1" and ends at "Character Position pos2".
I tested with
load data
CHARACTERSET AL32UTF8
LENGTH SEMANTICS CHARACTER
replace ...
in the .ctl file, but when the first character with more than one byte encoding (for example ü ) is in the file, all positions of that record are mixed up.
Is there a way to load these files in UTF8 without changing the file-definition to a column-seperator?
Thanks for any hints - charly

I have not tested this but you should be able to achieve what you want by using LENGTH SEMANTICS CHARACTER and by specifying field lengths (e.g. CHAR(5)) instead of only their positions. You could still use the POSITION(*+n) syntax to skip any separator columns that contain only spaces or tabs.
If the above does not work, an alternative would be to convert all UTF8 files to UTF16 before loading so that they become fixed-width.

Import data from a Fixed Length File into Oracle database

Hi,
I would like to import data from a Fixed Length text file into a table using HTML DB application.
As of now, i have a .sql file(that uses external table) to import the data into Oracle tables
I would like to integrate this in my HTML DB application so that the user can directly import the data into the table.
Sample data
XXXYYYYZZZZZ
Data should be read to table that has
Col1 Col2 Col3
XXX YYYY ZZZZZ

Hi,
I would like to import data from a Fixed Length text
file into a table using HTML DB application.AFAIK, fixed length imports are not something you can do directly with the HTML DB tools or available APIs.
As of now, i have a .sql file(that uses external
table) to import the data into Oracle tables
I would like to integrate this in my HTML DB
application so that the user can directly import the
data into the table.Any fixed-length data needs to have a specification associated with it that indicates which character position begins a new column and what each column represents. Some also include what datatype should be used for each of those.
If you really want to do this I would suggest that you create a table that you can store the file spec in. It would probably have columns for field name, start position, length or end position, datatype and any alias/column name you might want to apply. You would then use this table in a PL/SQL procedure (probably a package with the main processing procedure and various supporting procedures/functions) to read the file into memory, apply the file spec to each line and then do inserts into your table.
Obviously, this is just a concept or strategy. Implementing it will depend on your PL/SQL skills and determination. If you want to pursue this strategy I'm sure you can find some jump-starts by doing a search on the PL/SQL forum.
This may not sound like an answer - but the answer is you need to code it to fit your requirements. Hope that helps.

Parameters for Ingesting wide fixed-length files?

I created an SSIS process to ingest fixed-length text files into this table.
CREATE TABLE [dbo].[Temp_Source_Fixed](
[Column 0] [text] NULL,
[ID] [int] IDENTITY(1,1) NOT NULL,
CONSTRAINT [Temp_Source_Fixed_ID] PRIMARY KEY CLUSTERED
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
It works fine with most of the files, but one file has almost 26000 characters per row and the process halts with a truncation error.
I suspect that if I change a parameter on the connection manager it will work, since I can manually use
the SSMS wizard to import manually if I specify Text Stream (DT_Text) for the data type of Column 0 versus String (DT_STR).
For the connection manager I have
In the connection string I have Provider=SQLNCLI10.1 and Auto Translate=False.
In Misc parameters, DelayValidation=False.
For the Data Flow Task I have
DefaultBufferSize is 10485760
Any ideas on what I need to change?
Thanks,
Jnana
Jnana Sivananda

You need the column in question defined in SSIS as DT_Text.
You need to either drop the flat file connector and re-do it with this datatype, or access the Advanced Editor input and output column and alter its datatype there

Issue with Mapping Spaces for Receiver Flat File Fixed Length

Hi Mapping experts,
my scenario is receiver FILE (fixed length)
so if a validation applied on a target field returns false then I need to pass the spaces having the number of characters defined for that field
example
targetField length = 8
using "IF" function to perform validation,   if validation is true THEN = FIELD
if validation is false ELSE = "________"    (underscore to represent 8 spaces)
the problem is the validation is of multiple occurences in one queue and if the "true" statement is on the 6th row, I get _________ which is the value of the 1st row (which is correct because rows 1 to 5 are all false therefore having the value of ELSE which is _______ mapped to it)
How can I get the value of the TRUE row regardless of what row it is located?
e.g. IF = input is 5 rows of validation,     TRUE is in the 3rd row,   i will get the 3rd row value
       IF = input is 5 rows of validation,     NO TRUE Value,   return 8 spaces
right now when i Display Queue values are
iF:in0          iF:in1          iF:in2          iF:out
1111          false          [_________]     [_________]
2222          false                    [_________]
3333          true                    3333
4444          false                    [_________]
5555          false                    [_________]
In above Queue i only get the value of the 1st row which is ________   --> because my target field occurrences definition in Data Type is 0....1
if I change Data Type occurrences to 1...unbounded I get 5 target fields generated --> WRONG because target file is fixed field, so only one occurence of that target field is required

Can you give me the idea of what validation are you using so that anyone can help you with the UDF straightaway
because you need to have a UDf in place which will iterate the number of times the field occurs and then it will check the entire queue first ,where validation is true and only at the instant it will return the value
if the entire queue is value it will return the 8 underscores
I hope this is what you wanted

Can Open Hub create a fixed length file, not CSV?

I've been given a requirement to produce a file that is not a CSV file, but a file of a fixed length where all of the fields are always in the same positions.
For example, a material "batch" number can be of variable length. They want it to always appear on the file in positions 10-20, even if in some cases it is 10 digits and in other cases it is 4 digits. There should be spaces to fill in the remaining digits.
Can the Open Hub BADI be used to do this? It seems like it always wants to compress the data (so to speak) and stick a seperator in there and the BADI is not helping.
Thanks for your help!

Gui_download issue - trailing spaces getting truncated for fixed length fil

Hi All,
I have a requirement where I need to download an internal table as a fixed length file.
The code is as follows:
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
BIN_FILESIZE =
FILENAME = L_FILE
FILETYPE = 'ASC'
APPEND = 'X'
WRITE_FIELD_SEPARATOR = ' '
HEADER = '00'
TRUNC_TRAILING_BLANKS = ' '
WRITE_LF = ' '
COL_SELECT = ' '
COL_SELECT_MASK = ' '
DAT_MODE = ' '
IMPORTING
FILELENGTH =
TABLES
DATA_TAB = IT_TEXT
EXCEPTIONS
FILE_WRITE_ERROR = 1
NO_BATCH = 2
GUI_REFUSE_FILETRANSFER = 3
INVALID_TYPE = 4
NO_AUTHORITY = 5
UNKNOWN_ERROR = 6
HEADER_NOT_ALLOWED = 7
Each row in the internal table IT_TEXT is 242 chars long.
The FM is truncatinf the trailing blanks on the file. How do I get the FM to not truncate the trailing blanks in each row?
My internal table has multiple rows and the number of rows on the table should be same as the number of rows on the downloaded file.
I tried setting the WRITE_LF parameter to space.
In this case, the trailing spaces are not truncated(which is as per my requirement), BUT all the rows in the internal table appear in a single line on the downloaded file instead of multiple rows.
I also tried setting the TRUNC_TRAILING_BLANKS field to space but that does not work either. Spaces at the end of the row are still truncated.
so the requirement is: the spaces at the end of each row should not be truncated and
each row on the internal table should have a corresponding row on the downloaded file.
(it is a fixed length file)
I also tried using the following code
class cl_abap_char_utilities definition load.
DATA: BEGIN OF IT_TEXT OCCURS 0,
       TEXT(242) TYPE C,
       cr_lf TYPE c VALUE cl_abap_char_utilities=>cr_lf,
      END OF IT_TEXT.
when i compile, i get the following error
The type "CL_ABAP_CHAR_UTILITIES" is unknown.
Im using R/3 4.6C. Could this be a problem?
Please suggest a solution for this problem.
Thanks!

XSLT Mapping : XML to Fixed Length File

Hi,
I have to code a XSLT mapping which converts the XML into a Fixed Length File Format. I am getting the output but it has some garbage values (Some extra spaces in front of first record and also extra blank lines before the first record)

hi,
>>>>
<xsl:output method="text" indent="yes" media-type="text/plain"/>
you allow the spaces by using indent="yes"
try with indent="no"
