How To Fix RSAN_RT513 - In the aggregation, there are duplicate char. values for field &1

SAP Error Message - Details

• Message type: E = Error

• Message class: RSAN_RT - Messages for Runtime Analysis

• Message number: 513

• Message text: In the aggregation, there are duplicate char. values for field &1

What causes this issue?

In the aggregation node &V2&, the aggregation relationship NOP (No
Operation) was specified for field &V1&. Aggregation NOP means that
aggregation is not permitted for that particular field.
In this way, you can ensure, for example, that the currency is the same
in all records.
If this case arises, the assessment of the analysis process is
terminated.

System Response

The analysis process is terminated because the data is not allowed to
be summarized for characteristic &V1&.

How to fix this error?

Change the definition of the analysis process. If you want to produce
several records, change the definition of the analysis process by
deleting field &V1& from the list of aggregation fields and adding it
instead to the list of grouping fields.

• What is the cause and solution for SAP error message RSAN_RT513 - In the aggregation, there are duplicate char. values for field &1 ?

  The SAP error message RSAN_RT513 indicates that there are duplicate characteristic values for a specific field during the aggregation process in SAP BW (Business Warehouse). This typically occurs when the data being processed contains multiple entries for the same characteristic value, which can lead to ambiguity in the aggregation results.
  Cause:
  
  Duplicate Data: The most common cause of this error is that the data source contains duplicate entries for the characteristic values being aggregated. This can happen due to incorrect data loading, data modeling issues, or issues in the source system.
  Incorrect Data Model: The InfoObject or InfoProvider may not be set up correctly, leading to duplicates in the data model.
  Aggregation Settings: The aggregation settings in the query or the InfoCube may not be configured to handle duplicates properly.
  
  Solution:
  
  Check Data Source: Review the data source to identify and eliminate duplicate entries. You can use transaction codes like RSA1 (Data Warehousing Workbench) to analyze the data.
  Data Cleansing: Implement data cleansing processes to ensure that duplicates are removed before loading data into the InfoCube or DataStore Object (DSO).
  Aggregation Settings: Review the aggregation settings in the query or InfoProvider. Ensure that the aggregation logic is correctly defined to handle duplicates.
  Use Distinct Values: If applicable, modify the query to use distinct values for the characteristic in question. This can be done in the query designer by adjusting the aggregation settings.
  Check for Data Modeling Issues: Ensure that the data model is correctly designed, and that relationships between InfoObjects are properly defined to avoid duplicates.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 for data modeling and monitoring, and RSRV for checking data consistency.
  SAP Notes: Check for relevant SAP Notes that may address specific issues related to this error message.
  Documentation: Refer to SAP BW documentation for best practices on data modeling and aggregation to prevent such issues in the future.
  Performance Considerations: Be aware that handling duplicates can impact performance, so ensure that any solutions implemented are efficient.
  
  By following these steps, you should be able to resolve the RSAN_RT513 error and ensure that your aggregation processes run smoothly without encountering duplicate characteristic values.
