 Work item 000004662869: Object PRD300    BUS2089   000964030000114012 method
 ZTRY_AUTO_APPROVE cannot be executed
 
     Message no. WL 821
 
 Diagnosis
 
     The call of the object methods for the work item ended with a return code
     for which there is no handling defined in the workflow. This is regarded
     as an error by the work item manager (WIM).
 
 System response
 
     The work item was set to error status, the return values from the object
     method were saved.
 
 Procedure
 
     Check the saved return values of the object method. In particular, check
     whether
        -  an application (ERRORCODE = 1) or
        -  a system error (ERRORCODE = 2) is involved.
 
 In the case of an application error, please check either your workflow
 definition or the implementation of your object methods.
 
 In the case of a system error, please contact your workflow system
 administrator. In this case also check whether there is an error in the
 binding definition between task and method.
