• What is the cause and solution for SAP error message RSRV122 - Key figure &1 has type integer and therefore has no unit ?

  The SAP error message RSRV122 indicates that there is a key figure in your data model that is defined as an integer type, which means it cannot have a unit of measure associated with it. This can occur in SAP BW (Business Warehouse) or SAP BI (Business Intelligence) environments when working with InfoObjects, queries, or data models.
  Cause:
  
  Data Type Mismatch: The key figure is defined as an integer, which is typically used for counting or whole number values. However, it is being treated or expected to have a unit of measure (like currency, weight, etc.), which is not applicable for integer types.
  Modeling Error: During the modeling of InfoObjects or queries, there may have been an oversight where a key figure was incorrectly set up to expect a unit of measure.
  Data Source Issues: The data source feeding into the key figure may have been incorrectly configured, leading to a mismatch in expected data types.
  
  Solution:
  
  
  Check Key Figure Definition: 
  
  Go to the InfoObject definition for the key figure in question and verify its data type. If it is indeed set as an integer and should have a unit of measure, consider changing its data type to a decimal or a type that supports units.
  
  
  
  Adjust Query Settings:
  
  If the key figure is being used in a query, check the query settings to ensure that it is not incorrectly configured to expect a unit of measure. You may need to remove any unit of measure settings associated with this key figure.
  
  
  
  Review Data Source:
  
  Check the data source that populates this key figure. Ensure that the data being fed into it is appropriate for its defined type. If the data source is providing values that should have a unit, consider adjusting the data model accordingly.
  
  
  
  Re-Modeling:
  
  If necessary, you may need to re-model the InfoObject or the query to ensure that the key figure is correctly defined and used.
  
  
  
  Testing:
  
  After making changes, test the query or report to ensure that the error is resolved and that the key figure behaves as expected.
