• What is the cause and solution for SAP error message R8123 - InfoObject &: Assigned unit does not exist ?

  The SAP error message R8123, which states "InfoObject &: Assigned unit does not exist," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an issue with the unit of measure assigned to a characteristic or InfoObject. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing Unit of Measure: The error usually indicates that the unit of measure (UoM) assigned to a particular InfoObject does not exist in the system. This can happen if the unit was deleted or not properly defined in the master data.
  Incorrect Configuration: The InfoObject may be incorrectly configured, leading to a mismatch between the expected and actual units of measure.
  Data Load Issues: During data loading processes, if the source data contains units that are not defined in the target InfoObject, this error can occur.
  Transport Issues: If the InfoObject was transported from one system to another (e.g., from development to production) and the unit of measure was not included in the transport, it may lead to this error.
  
  Solution:
  
  
  Check Unit of Measure:
  
  Go to the transaction code CUNI (Unit of Measure) in SAP.
  Verify if the unit of measure assigned to the InfoObject exists. If it does not, you may need to create it or restore it if it was deleted.
  
  
  
  Review InfoObject Configuration:
  
  Use transaction code RSA1 to access the Data Warehousing Workbench.
  Navigate to the InfoObject in question and check its settings, especially the unit of measure settings.
  
  
  
  Data Source Validation:
  
  Check the data source from which the data is being loaded. Ensure that the units of measure in the source data match those defined in the target InfoObject.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, ensure that all necessary objects, including units of measure, were included in the transport request.
  
  
  
  Re-activate InfoObject:
  
  Sometimes, reactivating the InfoObject can resolve inconsistencies. You can do this in the Data Warehousing Workbench.
