Reading files in application server

Former Member — Wed, 24 Aug 2005 11:05:05 GMT

Hi All,

In connection with my yesterday's post of how to read a tab delimited file from

application server, I have this question.

How do we save a file as a tab delimited file in the application server because

yesterday's suggestions don't seem to work because even though I applied the logic

suggested it doesn't work out so I feel there is a problem in the files being saved in

application server. I am attaching yesterday's discussion. Please suggest.

Regards,

Karthik

Reading file from Application Server

Posted: Aug 23, 2005 12:41 PM Reply E-mail this post

Hi All,

I have an old program which is throwing up an issue.

I am succesfully uploading a tab-delimited(DAT) text file from a local server using the

'UPLOAD' Function Module. But when I try to use the same file saved in the application

server and upload it using 'OPEN DATASET P_FILE FOR INPUT IN TEXT MODE' statement and

next 'READ DATASET P_FILE INTO INT_TABLE', it is not considering the tab-delimiters and

reading the adjacent fields into a single field using # as the separator

For example in the text file I have 3 fields

Field1 Field2 Field3

AAAAA BBBBB CCCCC

After the READ DATASET statement the work area is being populated as <wa>-field1 =

AAAAA#BB

<wa>-field2 = BBB#CCC

<wa>-field3 = CC

The field length's of the 3 fields are 8, 7 & 7 respectively.

Could you suggest me a solution such that the fields are populated as below

<wa>-field1 = AAAAA

<wa>-field2 = BBBBB

<wa>-field3 = CCCCC

Thanks,

Karthik

may be you have to split it manually

split <text> at CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB into filed1 field2 field3 etc.

Hi,

Open the dataset in IN BINARY MODE ( not in text mode ) and use SPLIT stmt at tab.

Hi,

I will try this, but could you please explain what is the significance of '09'. I have

not understood that.

Thanks,

Hi,

data: hor_tab type x value '09'.

is the hex value of horizontal tab. When you work in binary mode you can read this

values and split your fields at it.

Hi,

Did you try to read it in binary mode ?

OPEN DATASET P_FILE FOR INPUT IN BINARY MODE
