• What is the cause and solution for SAP error message RSTRAN519 - Rule (target field: &2): No target unit assigned ?

  The SAP error message RSTRAN519 indicates that there is an issue with the data transfer process, specifically related to the assignment of target units in a data transfer rule. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when you are trying to load data into a target InfoObject or InfoProvider, and the system cannot find a valid target unit for the specified field.
  Cause:
  The error message "No target unit assigned" usually arises due to one of the following reasons:
  
  
  Missing Target Unit Assignment: The target field in the data transfer rule does not have a unit assigned to it. This can happen if the target field is expected to hold a unit of measure but none has been defined.
  
  
  Incorrect Data Transfer Rule Configuration: The data transfer rule may not be properly configured, leading to the absence of a target unit for the specified field.
  
  
  Data Source Issues: The data source from which you are trying to load data may not have the necessary unit information, or the mapping between the source and target fields may be incorrect.
  
  
  Field Type Mismatch: There may be a mismatch between the field types in the source and target, which can lead to issues in unit assignment.
  
  
  Solution:
  To resolve the RSTRAN519 error, you can follow these steps:
  
  
  Check Target Field Configuration:
  
  Go to the target InfoObject or InfoProvider in the SAP BW system.
  Ensure that the target field (as indicated by &2 in the error message) has a unit of measure assigned. You can do this by checking the field's properties in the InfoObject definition.
  
  
  
  Review Data Transfer Rule:
  
  Open the data transfer rule that is causing the error.
  Verify that the mapping for the target field is correctly set up and that the target unit is specified.
  
  
  
  Assign a Unit of Measure:
  
  If the target field requires a unit of measure, assign the appropriate unit in the target field settings. This can usually be done in the InfoObject maintenance transaction (e.g., RSA1).
  
  
  
  Check Source Data:
  
  Ensure that the source data contains the necessary unit information. If the source does not provide units, you may need to adjust the data source or the transformation logic.
  
  
  
  Test the Data Load:
  
  After making the necessary adjustments, test the data load again to see if the error persists.
  
  
  
  Consult Documentation:
  
  If you are still facing issues, refer to SAP documentation or consult with your SAP BW administrator for further assistance.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like RSA1 (Data Warehousing Workbench) to access InfoObjects and data transfer rules.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Data Modeling: Understanding the data modeling concepts in SAP BW can help in configuring InfoObjects and data transfer rules correctly.
  
  By following these steps, you should be able to identify and resolve the cause of the RSTRAN519 error in your SAP BW environment.
