  The SAP error message RSAU185 "No formula assigned to key field & (data field &)" typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with InfoObjects, especially when defining or modifying key figures or characteristics in a data model.
  Cause:
  This error indicates that there is a key field in your data model that does not have an associated formula defined for it. This can happen in various scenarios, such as:
  
  Missing Formula Assignment: The key figure or characteristic is expected to have a formula for calculations, but none has been assigned.
  Incorrect Configuration: The configuration of the InfoObject or the data model may be incomplete or incorrect.
  Data Source Issues: The data source from which the data is being pulled may not be properly configured to provide the necessary calculations.
  
  Solution:
  To resolve the RSAU185 error, you can follow these steps:
  
  
  Check InfoObject Configuration:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1).
  Locate the InfoObject that is causing the error.
  Ensure that a formula is assigned to the key field. If not, you will need to create or assign a formula.
  
  
  
  Assign a Formula:
  
  If a formula is missing, you can create a new formula or assign an existing one.
  Navigate to the "Formula" tab in the InfoObject maintenance screen and define the necessary calculations.
  
  
  
  Review Data Source:
  
  Check the data source that is being used to populate the InfoObject.
  Ensure that it is correctly configured and that it can provide the necessary data for the key field.
  
  
  
  Re-activate the InfoObject:
  
  After making changes, you may need to re-activate the InfoObject to ensure that the changes take effect.
  
  
  
  Check for Dependencies:
  
  If the key field is dependent on other fields or calculations, ensure that those dependencies are correctly defined and active.
  
  
  
  Test the Changes:
