Smart SAP Assistant

• What is the cause and solution for SAP error message CRM_MKTCCM_JOB_MSG018 - Job instance already created with another value (&1) for weak_read_only ?

  The SAP error message CRM_MKTCCM_JOB_MSG018 indicates that a job instance has already been created with a different value for the parameter weak_read_only. This typically occurs in the context of the SAP Customer Relationship Management (CRM) system, particularly when dealing with marketing campaigns or similar processes that involve job scheduling.
  Cause:
  The error arises when:
  
  A job instance is being created or scheduled, but there is already an existing job instance with the same identifier that has been configured with a different value for the weak_read_only parameter.
  The system enforces a rule that prevents multiple job instances from being created with conflicting configurations to avoid data inconsistency or conflicts in processing.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Job Instances:
  
  Use transaction codes like SM37 (Job Monitoring) to check for existing job instances that may be running or scheduled. Look for jobs with the same name or identifier.
  
  
  
  Review Job Parameters:
  
  Identify the parameters used for the existing job instance, particularly the weak_read_only parameter. Ensure that the new job you are trying to create uses the same value for this parameter.
  
  
  
  Modify or Delete Existing Job:
  
  If the existing job is no longer needed, you can delete it or modify its parameters to match the new job you want to create. Be cautious with this step to avoid disrupting any ongoing processes.
  
  
  
  Use a Different Job Identifier:
  
  If it is not feasible to change the existing job, consider using a different job identifier for the new job instance you are trying to create.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to job scheduling and the specific error message for any additional insights or recommendations.
