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.
