• Message text: Writing with delta determination is not possible in the update task

What causes this issue?

Module RSDRI_CUBE_WRITE_PACKAGE or class CL_RSDRI_INFOCUBE has been
called in an update task, whereas deltas should be found and written to
the Cube (parameter i_delta = rs_c_true ).

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

This is not possible in the update task, as COMMITS have to be performed
when finding the delta.

• What is the cause and solution for SAP error message DBMAN973 - Writing with delta determination is not possible in the update task ?

  The SAP error message DBMAN973 ("Writing with delta determination is not possible in the update task") typically occurs in the context of data updates in SAP systems, particularly when dealing with delta updates in the context of data extraction or data transfer processes. This error can arise in various scenarios, such as during the execution of update tasks in SAP BW (Business Warehouse) or when using SAP Data Services.
  Causes:
  
  Delta Mechanism Issues: The error often indicates that the delta mechanism is not functioning correctly. This could be due to issues with the delta queue or the delta initialization process.
  Data Consistency Problems: If there are inconsistencies in the data being processed, it may prevent the delta determination from being executed properly.
  Configuration Errors: Incorrect configuration settings in the data source or the update process can lead to this error.
  Locks or Conflicts: If there are locks on the data or conflicts with other processes trying to access the same data, it may result in this error.
  Missing or Incomplete Initialization: If the delta initialization has not been performed correctly, the system may not be able to determine the changes.
  
  Solutions:
  
  Check Delta Initialization: Ensure that the delta initialization has been performed correctly. If not, you may need to reinitialize the delta process.
  Review Configuration Settings: Verify the configuration settings for the data source and the update task. Ensure that they are set up correctly for delta processing.
  Monitor Delta Queue: Check the delta queue for any inconsistencies or errors. You can use transaction codes like RSA7 to monitor the delta queue.
  Resolve Locks: Investigate if there are any locks on the data that could be causing the issue. You can use transaction SM12 to check for and resolve any locks.
  Check for Data Consistency: Ensure that the data being processed is consistent and does not have any issues that could prevent delta determination.
  Re-run the Update Task: After addressing any issues, try re-running the update task to see if the error persists.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA7 (for monitoring delta queues), SM12 (for checking locks), and RSC3 (for monitoring data loads).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error. SAP Notes can provide specific guidance or fixes for known problems.
  Documentation: Review SAP documentation related to delta processing and update tasks for best practices and troubleshooting steps.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or BW team for further investigation, as they may have access to logs and additional tools to diagnose the problem.
