Category ABAP Programming Error
Runtime error PERFORM_CONFLICT_UC_STRUCT
Exception CX_SY_DYN_CALL_ILLEGAL_TYPE
ABAP program SAPLSDHI
Application Component BC-DWB-DIC-F4

|    Structure type conflict when calling a FORM.

|    An exception has occurred which is explained in more detail below. The                        |
|    exception is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE' and was not                      |
|     caught in procedure                                                                          |
|    "F4IF_FIELD_VALUE_REQUEST" "(FUNCTION)", nor was it propagated by a RAISING                   |
|     clause.                                                                                      |
|    Since the caller of the procedure could not have anticipated this                             |
|    exception, the current program was terminated.                                                |
|    The reason for the exception is:                                                              |
|    The FORM call "CALLBACK_F4_TARKZ_I" is incorrect:                                             |
|    The actual parameter (number 2) in the PERFORM is not compatible with                         |
|    the structure type required by FORM "CALLBACK_F4_TARKZ_I".                                    |
|    FORM "CALLBACK_F4_TARKZ_I" is defined in program "SAPLKMA6".                                  |
|    This error occurs in Unicode when the Unicode fragment view of the                            |
|    types is not compatible.                                                                      |
