Runtime Errors         PERFORM_NOT_FOUND
Exception              CX_SY_DYN_CALL_ILLEGAL_FORM
Date and Time          03/20/2009 01:31:52
Short text
     Call (PERFORM) to a non-existent routine.
What happened?
     There exist various options:
     Error in the ABAP Application Program
     The current ABAP program "RSDBRUNT" had to be terminated because it has
     come across a statement that unfortunately cannot be executed.
     or
     Error in the SAP kernel.
     The current ABAP "RSDBRUNT" program had to be terminated because the
     ABAP processor detected an internal system error.
What can you do?
     Note down which actions and inputs caused the error.
     To process the problem further, contact you SAP system
     administrator.
     Using Transaction ST22 for ABAP Dump Analysis, you can look
     at and manage termination messages, and you can also
     keep them for a long time.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_FORM', was
     not caught in
    procedure "%_LDB_CALLBACK" "(FORM)", 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:
    The program "RSDBRUNT" is meant to execute an external PERFORM,
    namely the routine "CB_DDF_GET_KNA1 " of the program "RFITEMAP ", but
    this routine does not exist.
    This may be due to any of the following reasons:
    1. One of the programs "RSDBRUNT" or "RFITEMAP " is currently being developed.
    The name "CB_DDF_GET_KNA1 " of the called routine may be incorrect, or
    the routine "CB_DDF_GET_KNA1 " is not yet implemented in the program "RFITEMAP
    2. If the program SAPMSSY1 is involved in the runtime error, one of
    the function modules called via RFC is not flagged as remote-capable.
    (see Transaction SE37  Goto -> Administration -> RFC flag)
    3. There is an inconsistency in the system. The versions of the
    programs "RSDBRUNT" and "RFITEMAP " do not match.
How to correct the error
    - Check that transports to the system are complete.
    - Conclude any developments already begun ("RSDBRUNT" and/or "RFITEMAP ").
    - Check routine names
    If the error occures in a non-modified SAP program, you may be able to
    find an interim solution in an SAP Note.
    If you have access to SAP Notes, carry out a search with the following
    keywords:
    "PERFORM_NOT_FOUND" "CX_SY_DYN_CALL_ILLEGAL_FORM"
    "RSDBRUNT" or "RSDBRUNT"
    "%_LDB_CALLBACK"
    If you cannot solve the problem yourself and want to send an error
    notification to SAP, include the following information:
    1. The description of the current problem (short dump)
       To save the description, choose "System->List->Save->Local File
    (Unconverted)".
    2. Corresponding system log
       Display the system log by calling transaction SM21.
       Restrict the time interval to 10 minutes before and five minutes
    after the short dump. Then choose "System->List->Save->Local File
    (Unconverted)".
    3. If the problem occurs in a problem of your own or a modified SAP
    program: The source code of the program
       In the editor, choose "Utilities->More
    Utilities->Upload/Download->Download".
Information on where terminated
    Termination occurred in the ABAP program "RSDBRUNT" - in "%_LDB_CALLBACK".
    The main program was "RFITEMAP ".
    In the source code you have the termination point in line 5433
    of the (Include) program "RSDBRUNT".
Error occurred during batch input processing
    The termination is caused because exception "CX_SY_DYN_CALL_ILLEGAL_FORM"
     occurred in
    procedure "%_LDB_CALLBACK" "(FORM)", but it was neither handled locally nor
     declared
    in the RAISING clause of its signature.
    The procedure is in program "RSDBRUNT "; its source code begins in line
    5414 of the (Include program "RSDBRUNT ".

Answer 1

hi,
Seems like you are trying to call a FORM...ENDFORM of another program.
In order to catch this exception, use IF FOUND option in your call.
CALL PERFORM(PROGRAM) IF FOUND.
This way it calls the form if it exists else it does nothing and there would be no dump.
Seems like the program you are calling has no PERFORM with name you specified.
