• What is the cause and solution for SAP error message RSTRAN553 - Rule (target field: &2 group: &3): Hierarchy split not possible ?

  The SAP error message RSTRAN553 indicates that there is an issue with a hierarchy split in a data transfer process, specifically when trying to assign a target field in a transformation. This error typically occurs in the context of data extraction and transformation processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error message "Hierarchy split not possible" usually arises due to one of the following reasons:
  
  
  Hierarchy Structure Issues: The hierarchy structure defined in the source system does not match the expected structure in the target system. This can happen if there are changes in the hierarchy or if the hierarchy is not properly defined.
  
  
  Inconsistent Data: The data being transferred may contain inconsistencies or invalid entries that prevent the hierarchy from being split correctly.
  
  
  Missing Hierarchy Nodes: If the target field expects certain hierarchy nodes that are not present in the source data, the transformation cannot proceed.
  
  
  Transformation Rules: The transformation rules defined in the data transfer process may not be correctly set up to handle the hierarchy.
  
  
  Solution:
  To resolve the RSTRAN553 error, you can take the following steps:
  
  
  Check Hierarchy Definitions: Verify that the hierarchy definitions in both the source and target systems are consistent. Ensure that all necessary nodes are present and correctly defined.
  
  
  Review Transformation Rules: Examine the transformation rules in the data transfer process. Make sure that they are correctly set up to handle the hierarchy and that there are no missing mappings.
  
  
  Data Consistency Check: Perform a data consistency check on the source data to identify any invalid entries or inconsistencies that may be causing the issue.
  
  
  Adjust Hierarchy Settings: If necessary, adjust the hierarchy settings in the target system to accommodate the incoming data. This may involve modifying the hierarchy structure or adding missing nodes.
  
  
  Test with Sample Data: If possible, test the transformation with a smaller set of sample data to isolate the issue and determine if it is related to specific entries.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for additional guidance on handling hierarchy-related errors in data transformations.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench) and RSC1 (InfoObject Maintenance) for managing hierarchies and transformations.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  
  By following these steps, you should be able to identify the root cause of the RSTRAN553 error and implement a solution to resolve it.
