  The SAP error message MDC_LOAD056 indicates that during a data load operation, duplicate records were found for a specific table, which caused the insertion to fail. This error typically occurs in the context of Master Data Consolidation (MDC) or when working with data models in SAP HANA.
  Cause:
  The error is caused by the presence of duplicate records in the source data that you are trying to load into the target table. This can happen due to various reasons, such as:
  
  Data Quality Issues: The source data may have been improperly cleaned or deduplicated, leading to multiple entries for the same key.
  Incorrect Data Mapping: The mapping of fields from the source to the target table may not be correctly defined, causing multiple records to be interpreted as unique.
  Concurrency Issues: If multiple processes are trying to insert records simultaneously, it may lead to duplicates being created.
  Business Logic Violations: The business rules defined for the target table may not allow for duplicate entries based on certain key fields.
  
  Solution:
  To resolve the MDC_LOAD056 error, you can take the following steps:

  Aggregating records.
  Keeping only the most recent or relevant record.
  Merging records based on business rules.
  
  
  
  Adjust Data Mapping: Review the data mapping configuration to ensure that it correctly reflects the structure of the target table and that it prevents duplicates from being created.
  
  
  Implement Constraints: If applicable, implement unique constraints on the target table to prevent future duplicates from being inserted.
  
  
  Test the Load Process: After making the necessary changes, test the data load process again to ensure that it completes successfully without errors.
