• What is the cause and solution for SAP error message RSRV121 - Key figure &1 has type number and therefore has no unit ?

  The SAP error message RSRV121 indicates that a key figure in your data model is defined as a numeric type but does not have an associated unit of measure. This can lead to issues in reporting and analysis, as key figures typically require a unit to provide context for the numerical values they represent.
  Cause:
  
  Key Figure Definition: The key figure is defined as a numeric type (e.g., integer, decimal) but lacks a unit of measure. This is often the case when the key figure is created without specifying a unit or when the unit is not properly assigned.
  Data Source Issues: The data source from which the key figure is derived may not provide a unit of measure, or the mapping of the unit may be incorrect.
  Modeling Errors: During the modeling of the InfoObject or InfoProvider, the unit of measure may have been omitted or incorrectly configured.
  
  Solution:
  
  
  Check Key Figure Definition:
  
  Go to the InfoObject maintenance (transaction code RSD1).
  Locate the key figure in question and check its properties.
  Ensure that a unit of measure is assigned to the key figure. If not, assign an appropriate unit.
  
  
  
  Modify Data Source:
  
  If the key figure is derived from a data source (e.g., a DSO or InfoCube), check the data source configuration to ensure that it includes the unit of measure.
  If necessary, adjust the data extraction logic to include the unit.
  
  
  
  Re-activate the InfoObject:
  
  After making changes to the key figure definition, you may need to re-activate the InfoObject to ensure that the changes take effect.
  
  
  
  Check Aggregation and Calculation Logic:
  
  If the key figure is calculated or aggregated from other key figures, ensure that the source key figures have the correct units assigned.
  
  
  
  Testing:
  
  After making the necessary changes, test the key figure in a report or query to ensure that it now displays correctly with the associated unit of measure.
  
  
  
  Related Information:
  
  Unit of Measure: In SAP BW, units of measure are essential for key figures to provide meaningful context. Common units include currency (e.g., EUR, USD), quantity (e.g., pieces, liters), and others.
  Data Modeling Best Practices: When designing data models in SAP BW, always ensure that key figures have appropriate units of measure to avoid confusion and errors in reporting.
  SAP Notes and Documentation: Check SAP Notes for any specific issues related to your version of SAP BW that may provide additional insights or solutions.
  
  By following these steps, you should be able to resolve the RSRV121 error and ensure that your key figures are correctly defined with the necessary units of measure.
