• What is the cause and solution for SAP error message DMC_MDS_MAINT_EVENT136 - There exist already a ME of either type 'U' or 'E'. No creation possible! ?

  The SAP error message DMC_MDS_MAINT_EVENT136 indicates that there is an attempt to create a Maintenance Event (ME) of type 'U' (Update) or 'E' (Error) when one already exists in the system. This typically occurs in the context of SAP Data Management or SAP Master Data Governance (MDG) when trying to create a new maintenance event while another one of the same type is already active.
  Cause:
  
  Existing Maintenance Event: The primary cause of this error is that there is already an active maintenance event of type 'U' or 'E' in the system. This prevents the creation of a new event of the same type until the existing one is resolved or completed.
  Concurrency Issues: If multiple users or processes are trying to create maintenance events simultaneously, it may lead to this error.
  System Configuration: There may be specific configurations or settings in the system that restrict the creation of multiple maintenance events of the same type.

  Use transaction codes like DMC_MAINT_EVENT or relevant reports to check for existing maintenance events of type 'U' or 'E'.
  Identify the active maintenance event and determine its status.
  
  
  
  Resolve Existing Events:
  
  If an existing maintenance event is no longer needed, you may need to complete or delete it, depending on your business process.
  If the event is still relevant, you may need to wait until it is processed or resolved before creating a new one.
  
  
  
  Review User Actions:
  
  Ensure that users are not trying to create multiple maintenance events simultaneously. Implementing proper user training and guidelines can help mitigate this issue.
