• What is the cause and solution for SAP error message MDG_SQD_DUPCHECK015 - Only one target record is allowed ?

  The SAP error message MDG_SQD_DUPCHECK015: "Only one target record is allowed" typically occurs in the context of SAP Master Data Governance (MDG) when there is an attempt to create or modify a record that violates the uniqueness constraints defined for the target data model. This error indicates that the system has detected multiple records that match the criteria for uniqueness, but only one record is allowed.
  Cause:
  
  
  Duplicate Records: The most common cause of this error is that there are multiple records in the target data model that match the criteria for uniqueness. For example, if you are trying to create a new vendor record, and there are already existing vendor records with the same unique identifier (like Vendor ID or Tax ID), the system will throw this error.
  
  
  Incorrect Data Mapping: If the data being processed does not map correctly to the target structure or if there are issues with the data being sent to the MDG process, it can lead to this error.
  
  
  Configuration Issues: The uniqueness constraints may not be configured correctly in the MDG data model, leading to unexpected behavior during data processing.
  
  
  Solution:
  
  
  Check for Duplicates: Review the existing records in the target data model to identify any duplicates. You can use transaction codes like SE16 or SE11 to query the relevant tables and check for existing records that match the criteria.
  
  
  Data Cleansing: If duplicates are found, you may need to clean up the data by either merging records or deleting unnecessary duplicates, depending on your business rules.
  
  
  Review Data Mapping: Ensure that the data being sent to the MDG process is correctly mapped and does not inadvertently create duplicates. Validate the data before processing.
  
  
  Adjust Configuration: If the uniqueness constraints are not set up correctly, you may need to adjust the configuration in the MDG data model. This may involve modifying the data model or the validation rules to ensure that they align with your business requirements.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to MDG and the specific data model you are working with for additional guidance on handling duplicates.
  
  
  Testing: After making changes, conduct thorough testing to ensure that the issue is resolved and that no new errors are introduced.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  MDG Configuration: Familiarize yourself with the configuration settings in the MDG application, especially those related to data modeling and validation rules.
  User Exits and BAdIs: If you have custom logic implemented, review any user exits or BAdIs that may affect the data processing and uniqueness checks.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
