• What is the cause and solution for SAP error message DHCDC_RT026 - Object &1 (&2); the values of two boundary keys are identical ?

  The SAP error message DHCDC_RT026 indicates that there is an issue with the boundary keys in a data model or data extraction process. Specifically, it means that two boundary keys are identical, which is not allowed in the context of the operation you are trying to perform. This can occur in various scenarios, such as when working with data models, data extraction, or reporting.
  Cause:
  The error typically arises from one of the following situations:
  
  Duplicate Boundary Keys: The system has detected that two boundary keys (which are supposed to be unique identifiers for data segments) have the same value. This can happen due to incorrect data entry, data corruption, or misconfiguration in the data model.
  Configuration Issues: There may be a misconfiguration in the data model or extraction settings that leads to the generation of identical boundary keys.
  Data Integrity Issues: The underlying data may have integrity issues, such as duplicates that violate the expected uniqueness of boundary keys.
  
  Solution:
  To resolve the DHCDC_RT026 error, you can take the following steps:
  
  
  Check Data Model Configuration:
  
  Review the configuration of the data model or extraction process to ensure that boundary keys are defined correctly and are unique.
  Ensure that the settings for the boundary keys are appropriate for the data being processed.
  
  
  
  Inspect Data for Duplicates:
  
  Analyze the data being processed to identify any duplicates in the boundary keys. You can use SQL queries or data analysis tools to find and resolve these duplicates.
  If duplicates are found, you may need to clean the data by removing or correcting the duplicate entries.
  
  
  
  Adjust Extraction Logic:
  
  If you are using a custom extraction logic or transformation, ensure that it correctly generates unique boundary keys. Modify the logic if necessary to prevent the generation of identical keys.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific module or process you are working with. There may be additional guidance or known issues related to this error.
