  Cause:
  
  
  Ambiguous Field Definitions: The error usually arises when there are multiple fields that could be interpreted as the "main field" in a query or data model. This can happen if there are multiple characteristics or key figures that are not clearly defined or if there are conflicting definitions in the data model.

  Solution:
  
  
  Review Query Design: Check the query definition in the Query Designer. Ensure that the main field is clearly defined and that there are no conflicting fields that could cause ambiguity.
