|Short Text |
| Access using a 'ZERO' object reference is not possible. |
----------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------
|What happened? |
| Error in the ABAP application program. |
| |
| The current ABAP program "CL_SWF_RUN_WFM================CP" had to be |
| terminated because it found a |
| statement that could not be executed. |
----------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------
|Error analysis |
| An exception has occurred in class "CX_SY_REF_IS_INITIAL". This exception was |
| not caught |
| in procedure "READ_WORKFLOW_DEFINITION" "(METHOD)" or 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 occurring was: |
| The reason for the exception is: |
| You are trying to access a component with a 'ZERO' object reference |
| (points to 'nothing'). |
| An object reference must point to an object (an instance of a class) |
| before it can be used to access a component. The reference has either |
| never been set, or it was set to 'ZERO' with a CLEAR statement. |
----------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------
|How to correct the error |
| If the exception cannot be prevented, "CX_SY_REF_IS_INITIAL" must be caught |
| within procedure "READ_WORKFLOW_DEFINITION" "(METHOD)" or declared in the procedure's |
| RAISING clause. |
| To prevent the exception, note the following: |
| |
| If the error occurs in one of your own ABAP programs or an SAP program |
| that you have modified, try to correct the error yourself. |
| If the error occurs in a non-modfied SAP program, you might be able to |
| find a solution in the SAP Notes system. If you have access to the SAP |
| Notes system, check there first using the following keywords: |
| |
| "OBJECTS_OBJREF_NOT_ASSIGNED_NO" CX_SY_REF_IS_INITIAL |
| "CL_SWF_RUN_WFM================CP" bzw. CL_SWF_RUN_WFM================CM00F |
| "READ_WORKFLOW_DEFINITION" |
| If you cannot solve the problem yourself, please send the following |
| information to SAP: |

|Information on where terminated |
| The termination occurred in ABAP program or include |
| "CL_SWF_RUN_WFM================CP", in "READ_WORKFLOW_DEFINITION". The |
| main program was "SAPMSSY1". |
| |
| In the source code, the termination point is in line 44 of include |
| "CL_SWF_RUN_WFM================CM00F". |
| include "CL_SWF_RUN_WFM================CM00F". |
| The termination is due to exception "CX_SY_REF_IS_INITIAL" occurring in |
| procedure "READ_WORKFLOW_DEFINITION" "(METHOD)", |
| but not being handled locally there or being declared in the RAISING |
| clause. |
| The procedure is in program "CL_SWF_RUN_WFM================CP". Its source |
| code begins in line 1 of |
