  • What is the cause and solution for SAP error message UR151 - DataSource does not have a valid time stamp (please check status) ?

    The SAP error message UR151 indicates that a DataSource does not have a valid timestamp, which typically means that the DataSource is not in a state that allows it to be used for data extraction or replication. This can occur in various scenarios, particularly when working with SAP BW (Business Warehouse) or SAP Data Services.

    Cause:

    1. DataSource Status: The DataSource may be in an inactive state or not properly activated. This can happen if changes were made to the DataSource but it was not reactivated.
    2. Timestamp Issues: The timestamp associated with the DataSource may be outdated or missing, which can occur if the DataSource was not properly updated after changes.
    3. Transport Issues: If the DataSource was transported from one system to another, it may not have been activated in the target system.
    4. Replication Issues: If the DataSource is linked to a source system, there may be issues with the replication process that prevent it from being updated correctly.

    Solution:

    1. Check DataSource Activation:

      • Go to the DataSource in the SAP BW system (transaction code RSA1).
      • Check the status of the DataSource. If it is inactive, activate it by selecting the DataSource and clicking on the "Activate" button.
    2. Check Timestamp:

      • Ensure that the DataSource has a valid timestamp. You can do this by checking the DataSource properties in RSA1.
      • If the timestamp is missing or invalid, re-activate the DataSource to generate a new timestamp.
    3. Transport Check:

      • If the DataSource was transported, ensure that it has been activated in the target system. You may need to re-activate it in the target system.
    4. Replication Check:

      • If the DataSource is linked to a source system, check the replication status. You can do this in the DataSource settings or by using transaction code RSO2.
      • If there are issues with the replication, resolve them and ensure that the DataSource is properly updated.
    5. Check for Errors:

      • Review the logs for any errors related to the DataSource. This can provide additional context on what might be causing the issue.
    6. Consult Documentation:

      • If the issue persists, consult SAP documentation or support for further troubleshooting steps specific to your version and configuration.

    Related Information:

    • Transaction Codes:
      • RSA1: Data Warehousing Workbench
      • RSO2: DataSource Maintenance
    • SAP Notes: Check for any relevant SAP Notes that may address known issues with DataSources and provide patches or updates.
    • SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.

    By following these steps, you should be able to resolve the UR151 error and ensure that your DataSource is properly configured for use.
