how to transfer the spool data to application server?

I have a requirement to transfer the spool data to Application server,

now i 'm using the below code.

CALL FUNCTION 'RSPO_RETURN_ABAP_SPOOLJOB'

EXPORTING

RQIDENT = G_RQIDENT

FIRST_LINE = 1

TABLES

BUFFER = IT_BUFFER.

OPEN DATASET p_name FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

IF sy-subrc NE 0.

MESSAGE 'Unable to find file path' TYPE 'S' DISPLAY LIKE 'E'.

ELSE.

LOOP AT IT_BUFFER INTO WA_BUFFER.

TRANSFER WA_BUFFER(1023) TO p_name LENGTH L_length.

ENDLOOP.

CLOSE DATASET p_name.

but the problem is the spool contains more than 1500 pages and its going to short dump.

is any other way to achieve this requirement ?
