• What is the cause and solution for SAP error message OL373 - Instance-independent attributes must be virtual ?

  The SAP error message OL373, which states "Instance-independent attributes must be virtual," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA modeling. This error arises when you are trying to define an attribute in a data model that is not set as virtual, but it is marked as instance-independent.
  Cause:
  In SAP BW or HANA, instance-independent attributes are those that do not depend on a specific instance of a master data object. They are typically used for attributes that are common across all instances of a master data object. The system requires that these attributes be defined as virtual to ensure that they can be reused across different instances without duplicating data.
  Solution:
  To resolve the OL373 error, you need to ensure that the instance-independent attributes are defined as virtual. Here are the steps to do this:
  
  
  Open the Data Model: Go to the relevant data model where the error is occurring.
  
  
  Locate the Attribute: Find the instance-independent attribute that is causing the error.
  
  
  Change Attribute Properties:
  
  Open the properties of the attribute.
  Look for an option or checkbox that indicates whether the attribute is virtual.
  Set the attribute to be virtual.
  
  
  
  Save and Activate: After making the changes, save the data model and activate it.
  
  
  Test the Model: Run a test to ensure that the error has been resolved and that the data model functions as expected.
  
  
  Related Information:
  
  
  Instance-Independent Attributes: These attributes are typically used for characteristics that do not change from one instance of a master data object to another. Examples include attributes like country or currency.
  
  
  Virtual Attributes: Virtual attributes are not physically stored in the database but are derived from other data. They are calculated at runtime, which allows for more efficient data storage and retrieval.
  
  
  SAP Documentation: For more detailed information, refer to the official SAP documentation or help portal, which provides guidelines on modeling in SAP BW and HANA.
