• What is the cause and solution for SAP error message RSRV123 - Key figure &1 has type date and therefore has no unit ?

  The SAP error message RSRV123 indicates that there is an issue with a key figure in your data model that is defined as a date type, but it is being treated as if it should have a unit of measure. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with InfoObjects, InfoCubes, or queries.
  Cause:
  
  Data Type Mismatch: The key figure is defined as a date type, which inherently does not have a unit of measure. However, it may be incorrectly configured or used in a context where a unit is expected.
  Modeling Error: The key figure might have been incorrectly modeled or defined in the InfoObject or InfoCube.
  Query Design: If the key figure is being used in a query, it may be included in a context that expects numerical values or measures with units.
  
  Solution:
  
  
  Check Key Figure Definition:
  
  Go to the InfoObject maintenance (transaction code RSD1) and check the definition of the key figure. Ensure that it is correctly defined as a date type and that it does not have any unit of measure assigned.
  
  
  
  Review Query Design:
  
  If the error occurs in a query, review the query design in the Query Designer. Ensure that the key figure is not being used in calculations or aggregations that expect a numeric value.
  Remove the key figure from any calculations or aggregations that require a unit of measure.
  
  
  
  Adjust Data Model:
  
  If necessary, consider adjusting the data model to ensure that date fields are used appropriately. For example, if you need to perform calculations based on dates, consider creating a separate key figure that represents the difference in days or another relevant metric.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the query or report again to ensure that the error is resolved.
