Read file from application server having long text

Privete_member__1259949 · ‎2013 Nov 04

Hi AbapGurus,

I have a ".txt" file in application server as shown below (headings are not there, only for reference provided here): -

PO_NUMBER PO_ITEM ACCTASSCAT ITEM_CAT MATERIAL SHORT_TEXT ITEM_TEXT QUANTITY PO_UNIT NET_PRICE MAT_GRP PLANT STGE_LOC DELIVERY_DATE

101#10#K#D#repair of machine#"Para 1

Call for Papers...

some more texts...

.....Very long text.....

........

#1#AU#500#01#1001#IM01#8/12/2013

I have a internal table in my program, the field ITEM_TEXT are of string/char(50000) type.

Now during reading file from application server using READ DATASET, it is giving dump.

I have used statements like this.

DATA ls_TEXT(5000) TYPE C.

** Opening file on application server

OPEN DATASET lv_filename FOR INPUT IN TEXT MODE ENCODING DEFAULT.

IF sy-subrc IS INITIAL.

DO.

READ DATASET lv_filename INTO ls_TEXT.

IF sy-subrc IS INITIAL.

** Spliting file into fields and then appending to form a internal table

SPLIT ls_TEXT AT cl_abap_char_utilities=>horizontal_tab INTO

gs_poitem-po_number

gs_poitem-po_item

gs_poitem-acctasscat

gs_poitem-item_cat

gs_poitem-material

gs_poitem-short_text

gs_poitem-item_text

gs_poitem-quantity

gs_poitem-po_unit

gs_poitem-net_price

gs_poitem-mat_grp

gs_poitem-plant

gs_poitem-stge_loc

gs_poitem-delivery_date.

APPEND gs_poitem TO gt_poitem.

CLEAR gs_poitem.

ELSE.

EXIT.

ENDIF.

ENDDO.

ENDIF.

Now the good thing is when it found # then it split into other fields, which is fine. but problem is when it found "Enter / New line" in ITEM_TEXT field then again it splits into other fields, which is wrong.

Also if I change "cl_abap_char_utilities=>horizontal_tab" to "#" then it doesn't split.

So Gurus, how can I read file from application server having one field containing very long text in internal table. or is there any other work around to read file.

If a sample code is there then it would be great helpful.

I have a feeling there is a limit of 1000 chars, but I may be wrong. Could you post your dump message (ST22) here so that I can delve further.

Also there is a difference anyway in your declaration:

READ DATASET lv_filename INTO ls_TEXT.

Thanks Anthony !!

the dump is : -

Short text
A character set conversion is not possible.

What happened?
At the conversion of a text from codepage '4110' to codepage '4103':

    - a character was found that cannot be displayed in one of the two
    codepages;
    - or it was detected that this conversion is not supported

    The running ABAP program 'ZPO_UPLOAD' had to be terminated as the
     conversion
    would have produced incorrect data.

    The number of characters that could not be displayed (and therefore not
    be converted), is 1. If this number is 0, the second error case, as
    mentioned above, has occurred.

Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_CONVERSION_CODEPAGE', was not
     caught in
    procedure "READ_FILE" "(FORM)", nor was it propagated by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    Characters are always displayed in only a certain codepage. Many
    codepages only define a limited set of characters. If a text from a
    codepage should be converted into another codepage, and if this text
    contains characters that are not defined in one of the two codepages, a
    conversion error occurs.

Moreover, a conversion error can occur if one of the needed codepages
'4110' or '4103' is not known to the system.

    If the conversion error occurred at read or write of screen, the file
    name was 'T:\Load_Files\PO Item.txt'. (further information about the
     file: "X 1563").

This explains some of the limitations:

Hi Anthony,

if I use variant IGNORING CONVERSION ERRORS in OPEN DATASET statement then dump will lost but the problem is when it split at # first line comes fine in internal table but other lines goes wrong. System breaks ITEM_TEXT field at Enter and append in other field (here in PO_NUMBER). like as shown below: -

PO_NUMBER PO_ITEM ACCTASSCAT ITEM_CAT MATERIAL SHORT_TEXT ITEM_TEXT QUANTITY PO_UNIT NET_PRICE MAT_GRP PLANT STGE_LOC DELIVERY_DATE
101 10 K D repairs "Para 1. " Coming correct in internal table
Call for P
Fusion 201

New call f

The call f

Fusion is

* Internat
* Internat
* National
* The Asso

All text comes in first PO_NUMBER field rather than ITEM_TEXT field in form of many rows in internal table.

however it should come like

101 10 K D repairs "Para 1. Call for P ...... * Asso " Only one record

If there is any other way to read a file from application server having long text in one of field then let me know. highly appreciated.

Have you tried this:

OPEN DATASET lv_filename FOR INPUT IN TEXT MODE ENCODING NON-UNICODE WITH SMART LINEFEED.

Also, in my first reply I mentioned difference in your data declaration where you have 5000, and 50000. Has this been corrected?
