Read Dataset problem??

Former Member — Wed, 17 Oct 2007 15:30:47 GMT

Hi All,

I am getting a short dump when I try "READ DATASET g_unixfile INTO internal-table." to read a file into an internal table.

I have opened the file using th code>>"OPEN DATASET g_unixfile FOR INPUT IN TEXT MODE ENCODING DEFAULT."

and closed it using>>"CLOSE DATASET g_unixfile."

I have used the G_unixfile as 104 Characters and internal table as:

DATA: BEGIN OF g_t_tdata OCCURS 50,

g_recdata(104),

END OF g_t_tdata.

Please can anyone tell why I am getting a Dump?? at Read dataset??

Regards,

Shashank.

Can you see what is the SY_SUBRC value returned after OPEN DATASET.

That might be 4 and because of this READ is failing.

Also make sure that file exists at the specified location.

hi,

Try increasing the size of the field of Internal table to fit the data in the file. So just check it out in this way

DATA: BEGIN OF g_t_tdata OCCURS 50,

g_recdata<b>(2000)</b>,

END OF g_t_tdata.

Hi,

Try by increasing field length

DATA: BEGIN OF g_t_tdata OCCURS 50, " Upload data into this itab

g_recdata(2000),

END OF g_t_tdata.

Hi Shashank,

Can you remove ENCODING DEFAULT and try.
