Hi Ravi,

declare one internal table with one field of type string

then append all the errors to one internal table

you can download that internal table with errors using GUI_DOWNLOAD

If you are talking about downloading a file,with the error messages,then do,

DATA : BEGIN OF IT_ERRORS OCCURS 0,

LINE TYPE STRING,

END OF IT_ERRORS.

OPEN DATASET.....

IF SY-SUBRC <> 0.

IT_ERR0R-LINE = 'file not found'.

append it_error.

ENDIF.

like that you have to append all the errors to IT_ERROR.

finally based on the user option,use GUI_DOWNLOAD to download this IT_ERROR table to presentation server or USE OPEN DATASET,TRANSFER,CLOSE to download it to application server

Hi ,

This post is follow up of previous post regarding creating error log file.

As you told if i create an internal table with one filed,

How can i upload somany errors and how can i seperate them.

For example...i have to raise this many errors:

1.If error in opening file using open data set.

2.if error in reading file using read data set

3.if failed to upload data from file into SAP

So wheere ever i have to raise error i have to upload to that error table.

So all these errors how can identify?..Will they display line by line in itab?..

normally if we get an error we dont proceed with the processing.in this case your error NO 2 will not come if you get error 1. will you agree?

in general,

if you still have many records to be populated that internal table,and you want to distinguish them,

you can added up the FILE NAME along with that text like,(check the below in BOLD)

1.If error in opening file using open data set <b><FILENAME></b>

2.if error in reading file using read data set <b><FILENAME></b>

etc..

so you can use CONCATENATE

<b>

CONCATENATE 
'error in opening file using open data set'
  V_FILENAME
  INTO IT_ERROR-TEXT.
append it_error.

</b>

Hi,

Check this :

if you want to capture errors while creating the file. check below code for this :

data : begin of i_errmsg occurs 0,
        x_msg(100) type c,
       end of i_errmsg.

1.Creating a File

OPEN DATASET x_file FOR output 
                            MESSAGE l_msg
                       IN text MODE ENCODING DEFAULT.
  x_RCODE = sy-subrc. 
  IF x_RCODE <> 0.
    <b>i_errmsg-x_msg = l_msg.
    append i_errmsg.</b>  
  endif.

2.Reading the file

OPEN DATASET x_file FOR input

MESSAGE l_msg

IN text MODE ENCODING DEFAULT.

x_RCODE = sy-subrc.

IF x_RCODE <> 0.

<b>i_errmsg-x_msg = l_msg.

append i_errmsg.</b>

endif.[/code]

internal table i_errmsg will contain the error message details.

Hello Ravi,

The best soln is to have two fields in your internal table one for ERRID and ERRMSG.

In the code you can populate the ERRMSG with the error text while you can manipulate the ERRID field depending on the type of the error. Eg. Error while opening the file can be FILEOPEN type error. Something related to data can be DATA etc. It purely depends on your requirement.

Last you can sort the table if you wish to display the error list on type or do not sort if you wish to display the log as in sequence.
