• What is the cause and solution for SAP error message RSLPO_DFG120 - Source object is inconsistent (actual='&1', target='&2') ?

  The SAP error message RSLPO_DFG120 indicates that there is an inconsistency between the source object and the target object in a data flow or transformation process. This error typically arises in the context of data extraction, transformation, and loading (ETL) processes, particularly when working with SAP Data Services or SAP BW (Business Warehouse).
  Cause:
  
  Inconsistent Data Structures: The source and target objects may have different structures, such as differing field names, data types, or lengths.
  Data Type Mismatch: The data types of the fields in the source object do not match those in the target object.
  Missing Fields: One of the objects may have fields that are not present in the other, leading to an inconsistency.
  Transformation Logic Issues: If there are transformations applied to the data, they may not be correctly defined or may not align with the source and target structures.
  Metadata Changes: Changes in the metadata of the source or target objects (like changes in the underlying database schema) that have not been reflected in the data flow configuration.
  
  Solution:
  
  Check Object Definitions: Review the definitions of both the source and target objects to ensure they are consistent in terms of structure, data types, and field names.
  Update Data Flow: If there have been changes to the source or target objects, update the data flow or transformation logic accordingly to reflect these changes.
  Validate Mappings: Ensure that all mappings between the source and target fields are correctly defined and that there are no missing or extra fields.
  Test Transformations: If transformations are applied, test them individually to ensure they are functioning as expected and not causing inconsistencies.
  Recreate Objects: In some cases, it may be necessary to recreate the source or target objects in the data flow to ensure they are correctly aligned.
  Check for Metadata Updates: If there have been recent changes to the underlying database or data model, ensure that the data flow is updated to reflect these changes.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common errors.
  Data Services Documentation: Refer to the SAP Data Services documentation for guidelines on managing data flows and transformations.
  Transaction Codes: Use transaction codes like RSA1 (for BW) or the Data Services Management Console to monitor and manage data flows.
  Logs and Traces: Review logs and traces for more detailed error messages that can provide additional context for the inconsistency.
  
  By following these steps, you should be able to identify and resolve the inconsistency causing the RSLPO_DFG120 error message.
