Error with the FIELD CAT function module.

Question

Hi folks,
This was the error message i had got from the FIELDCAT function module.
An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_READ_SRC_LINE_TOO_LONG', was
     not caught in
    procedure "K_KKB_FIELDCAT_MERGE" "(FUNCTION)", 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:
    There was an attempt to read program "/A1SSPC/ITP_SCH_REP" from the database.
    The READ REPORT statement allows you to copy a program text into an
    internal table. The occupied line length in the program text must not
    exceed the width of the internal table.
    The internal table "\FUNCTION=K_KKB_FIELDCAT_MERGE\DATA=???" is 72 characters
     wide. The program line is
    204 characters wide.
Reg,

You can do this
TYPE-POOLS:slis.
DATA: it_vabp TYPE STANDARD TABLE OF vbap WITH HEADER LINE.
DATA: it_fieldcat TYPE slis_t_fieldcat_alv.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
   i_program_name               = sy-repid
   i_internal_tabname           = 'IT_VBAP'
   i_inclname                   = sy-repid
  CHANGING
    ct_fieldcat                  = it_fieldcat
* EXCEPTIONS
*   INCONSISTENT_INTERFACE       = 1
*   PROGRAM_ERROR                = 2
