How To Fix DS520 - Title identical, header deleted

SAP Error Message - Details

• Message type: E = Error

• Message class: DS - Messages for Editing Text Elements in ABAP Programs

• Message number: 520

• Message text: Title identical, header deleted

What causes this issue?

For an existing program, you can define both the report title (text ID
'R') and the page headers (text ID 'T').
If no page headers are defined, the report title is output at
TOP-OF-PAGE. Consequently, it is not necessary to store identical
report and page headers.
If the system detects such a case during text maintenance, the page
headers are deleted.

• What is the cause and solution for SAP error message DS520 - Title identical, header deleted ?

  The SAP error message DS520 with the title "Identical, header deleted" typically occurs in the context of data processing, particularly when dealing with data records that have duplicate entries. This error is often encountered in the Data Services (DS) environment when loading or transforming data.
  Cause:
  The error message indicates that the system has detected duplicate records in the data being processed. Specifically, it suggests that the system has identified records with identical values in the key fields, leading to the deletion of one of the duplicate records to maintain data integrity.
  Solution:
  To resolve the DS520 error, consider the following steps:
  
  
  Identify Duplicate Records:
  
  Review the data source to identify the records that are causing the duplication. You can use SQL queries or data profiling tools to find duplicates based on the key fields.
  
  
  
  Modify Data Extraction Logic:
  
  Adjust the data extraction or transformation logic to ensure that duplicates are handled appropriately. This may involve:
  
  Adding filters to exclude duplicates.
  Using aggregation functions to consolidate duplicate records.
  Implementing a deduplication process before loading the data.
  
  
  
  
  
  Check Data Mapping:
  
  Ensure that the mapping of fields in your data flow is correct and that the key fields are defined properly. This will help the system recognize unique records.
  
  
  
  Review Data Quality:
  
  Assess the quality of the data being loaded. If the source data is inherently flawed (e.g., contains duplicates), consider cleaning the data before processing.
  
  
  
  Use Distinct Clause:
  
  If applicable, use a DISTINCT clause in your SQL queries to eliminate duplicates at the source level.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for specific guidance related to your version of SAP Data Services, as there may be version-specific considerations.
