How To Fix SCDT_MPNG1018 - Source table &1, field &2: Possible data loss in redistribution

SAP Error Message - Details

• Message type: E = Error

• Message class: SCDT_MPNG1 - Message Class for the Function Module scdt_mapping_check

• Message number: 018

• Message text: Source table &1, field &2: Possible data loss in redistribution

What causes this issue?

The field &V2& in the source table &V1& is shorter than the associated
target field &V3&.
If you also use the synchronization object for the redistribution, it
will truncate the contents of the field &V3& to the length of the field
&V2&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you also use the synchronization object for the redistribution,
ensure that truncating it will not cause any problems (e.g. in text
fields).

• What is the cause and solution for SAP error message SCDT_MPNG1018 - Source table &1, field &2: Possible data loss in redistribution ?

  The SAP error message SCDT_MPNG1018 indicates a potential data loss issue during the redistribution process of data from a source table. This typically occurs in the context of SAP Data Transfer processes, such as when using the SAP Data Services or SAP BW (Business Warehouse) systems.
  Cause:
  The error message SCDT_MPNG1018 is triggered when there is a mismatch between the data types or lengths of the source table field and the target table field during a redistribution operation. This can happen due to:
  
  Data Type Mismatch: The source field may have a larger data type or length than the target field, leading to potential truncation of data.
  Incompatible Data Formats: If the source data format does not match the expected format in the target, it can lead to data loss.
  Transformation Rules: If there are transformation rules applied that do not account for all possible values or formats of the source data, it can lead to data loss.
  
  Solution:
  To resolve the SCDT_MPNG1018 error, you can take the following steps:
  
  
  Check Data Types: Verify the data types and lengths of the source and target fields. Ensure that the target field can accommodate the data from the source field without truncation.
  
  
  Adjust Target Field: If necessary, modify the target field to match the data type and length of the source field. This may involve changing the schema of the target table.
  
  
  Review Transformation Logic: If there are any transformations applied during the data transfer, review them to ensure they are correctly handling all possible values from the source.
  
  
  Data Quality Checks: Implement data quality checks to identify any records that may cause issues during redistribution. This can help in preemptively addressing potential data loss.
  
  
  Testing: After making adjustments, perform a test redistribution to ensure that the error does not occur again.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidelines related to the version of SAP you are using, as there may be version-specific considerations.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered and resolved similar issues.
  Data Governance: Implement data governance practices to ensure that data integrity is maintained throughout the data transfer processes.
  
  By following these steps, you should be able to identify the root cause of the SCDT_MPNG1018 error and implement a solution to prevent data loss during redistribution.
