• What is the cause and solution for SAP error message USMDZ102 - Info objects for the characteristics of the query are not unique ?

  The SAP error message USMDZ102 indicates that there is an issue with the uniqueness of the InfoObjects used in a query. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when you are trying to execute a query that involves characteristics that are not uniquely defined.
  Cause:
  The error arises when the InfoObjects (characteristics) used in the query are not unique, meaning that there are multiple entries in the data model that correspond to the same characteristic values. This can happen due to:
  
  Duplicate Data: There may be duplicate records in the underlying data source.
  Incorrect Data Modeling: The InfoObjects may not be properly defined or linked in the data model.
  Aggregation Issues: If the query is trying to aggregate data that has non-unique characteristics, it can lead to this error.
  Hierarchy Issues: If the characteristics are part of a hierarchy and the hierarchy is not properly defined, it can lead to ambiguity.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check for Duplicates: 
  
  Review the underlying data in the InfoProvider (e.g., InfoCube, DSO) to identify any duplicate records for the characteristics in question.
  Use transaction codes like RSA1 (Data Warehousing Workbench) to analyze the data.
  
  
  
  Review Query Design:
  
  Open the query in the Query Designer and check the characteristics used. Ensure that they are correctly defined and that there are no unnecessary duplicates.
  Ensure that the characteristics are properly linked to the key figures in the query.
  
  
  
  Adjust Aggregation Settings:
  
  If applicable, adjust the aggregation settings in the query to ensure that it can handle non-unique values appropriately.
  
  
  
  Check Hierarchies:
  
  If the characteristics are part of a hierarchy, ensure that the hierarchy is correctly defined and that there are no issues with the hierarchy nodes.
  
  
  
  Data Modeling:
  
  Review the data model to ensure that the InfoObjects are correctly defined and that there are no issues with the relationships between them.
  
  
  
  Test the Query:
  
  After making the necessary adjustments, test the query again to see if the error persists.
