MCEX143 - Details

• The SAP error message MCEX143 indicates that a specific structure (denoted by &1) cannot be changed because there is existing data in delta management. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when you are trying to modify a data structure that is currently being used for delta processing.
  
  Cause:
  
  Delta Management: The structure you are trying to change is part of a delta process, which means that it is actively being used to track changes in the data. Delta management is used to efficiently load only the changes (inserts, updates, deletes) rather than the entire dataset.
  Existing Data: If there is already data in the delta queue or if the structure is linked to a data source that has been activated, you cannot make changes to it until the delta management is stopped or the data is cleared.
