Regarding 2LIS_03_BF short dump

Question

Hi Friends
Kindly help me in this regard, I got below short dump while executing "2LIS_03_BF" in RSA3 extract checker.
We wrote the customer exit for this data source, I put the debug point in my routine, but it not stopped. hope this error occuring before the routine. Please let me know the procedure what I should do here
Short dump:
Runtime Error          IMPORT_ALIGNMENT_MISMATCH
Exception              CX_SY_IMPORT_MISMATCH_ERROR
       Occurred on     31.07.2007 at   09:06:01
Error when importing object "MC03BF0_TAB".
What happened?
Error in ABAP application program.
The current ABAP program "SAPLMCEX" had to be terminated because one of the
statements could not be executed.
This is probably due to an error in the ABAP program.
Error analysis
An exception occurred. This exception is dealt with in more detail below
. The exception, which is assigned to the class 'CX_SY_IMPORT_MISMATCH_ERROR
was neither
caught nor passed along using a RAISING clause, in the procedure
"MCEX_BW_LO_API" "(FUNCTION)"
Since the caller of the procedure could not have expected this exception
to occur, the running program was terminated.
The reason for the exception is:
When importing object "MC03BF0_TAB", the structure did not match the
structure of the target object. The error occurred in component
no. 174.
This may be due to one of the following reasons:
- the structure is actually different (the next field has, for
  example, a different data type) or
- the same sequence of components were exported and imported,
  but the fields were from other include units.
How to correct the error
The exception must either be prevented, caught within the procedure
"MCEX_BW_LO_API"
"(FUNCTION)", or declared in the procedure's RAISING clause.
To prevent the exception, note the following:
There is a probably a new version of the program which does not
match the dataset. The data may not have been converted.
It is also possible that the field type of the imported field
has been changed in the ABAP/4 Dictionary.
Try to eliminate the error by regenerating the program "SAPLMCEX". To
do this, proceed as follows:
Call Transaction SE38 in the R/3 System, enter the program
name "SAPLMCEX" and then choose "Generate".
If the error occurred in one of your own programs or in an SAP program
that you modified, try to correct it yourself.
You may able to find an interim solution to the problem
in the SAP note system. If you have access to the note system yourself,
use the following search criteria:
"IMPORT_ALIGNMENT_MISMATCH" CX_SY_IMPORT_MISMATCH_ERRORC
"SAPLMCEX" or "LMCEXU06"
"MCEX_BW_LO_API"
Information on where terminated
The termination occurred in the ABAP program "SAPLMCEX" in "MCEX_BW_LO_API".
The main program was "RSFHGEN2 ".
The termination occurred in line 226 of the source code of the (Include)
program "LMCEXU06"
of the source code of program "LMCEXU06" (when calling the editor 2260).
Processing was terminated because the exception "CX_SY_IMPORT_MISMATCH_ERROR"
occurred in the
procedure "MCEX_BW_LO_API" "(FUNCTION)" but was not handled locally, not
declared in the
RAISING clause of the procedure.
The procedure is in the program "SAPLMCEX ". Its source code starts in line 5
of the (Include) program "LMCEX$06 ".
