  The SAP error message CD423, which states "Inconsistent sources of table &," typically occurs in the context of data modeling or when working with InfoObjects in SAP BW (Business Warehouse). This error indicates that there is an inconsistency in the data sources defined for a particular table or InfoObject.
  Cause:
  
  
  Inconsistent Data Sources: The error usually arises when the data sources for a particular InfoObject or table are not aligned or are incorrectly defined. This can happen if:

  There are multiple data sources pointing to the same InfoObject, but they are not compatible.
  The InfoObject is not properly activated or has not been updated after changes were made.
  
  
  
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), inconsistencies may arise if the transport did not include all necessary objects.
