• What is the cause and solution for SAP error message R8124 - InfoObject &: A unit was assigned with TYPE 'NUM' ?

  The SAP error message R8124 indicates that there is an issue with the assignment of a unit to an InfoObject in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). Specifically, the error states that a unit has been assigned to an InfoObject that is of type 'NUM' (numeric), which is not allowed.
  Cause:
  The primary cause of this error is that the InfoObject in question is defined as a numeric type, but it has been assigned a unit of measure. In SAP BW, units of measure can only be assigned to InfoObjects that are of type 'CHAR' (character) or 'CURR' (currency). Numeric InfoObjects are not designed to handle units, which leads to this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check InfoObject Definition:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1 or RSD1).
  Locate the InfoObject that is causing the error.
  Verify its data type. If it is set to 'NUM', you need to either change the data type or remove the unit assignment.
  
  
  
  Remove Unit Assignment:
  
  If the InfoObject is correctly defined as numeric and should not have a unit, remove the unit assignment from the InfoObject.
  This can typically be done in the InfoObject maintenance screen under the "Attributes" or "Units" tab.
  
  
  
  Change Data Type (if necessary):
  
  If the InfoObject should indeed have a unit of measure, consider changing its data type to 'CURR' (if it represents currency) or 'CHAR' (if it represents a character string).
  After changing the data type, you may need to reassign the unit of measure.
  
  
  
  Transport Changes:
  
  If you are working in a development environment, ensure that any changes made are transported to the appropriate environments (e.g., quality assurance, production) as needed.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the InfoObject to ensure that the error no longer occurs and that the data behaves as expected.
  
  
  
  Related Information:
  
  Data Types in SAP BW: Understanding the different data types and their appropriate use cases is crucial for effective data modeling in SAP BW.
  Units of Measure: Units of measure are typically used for InfoObjects that represent quantities, such as sales amounts, weights, or other measurable attributes.
  SAP Documentation: Refer to SAP Help documentation for detailed information on InfoObject types, units of measure, and best practices for data modeling in SAP BW.
  
  By following these steps, you should be able to resolve the R8124 error and ensure that your InfoObject is correctly configured for your reporting and analysis needs.
