Smart SAP Assistant

• What is the cause and solution for SAP error message CNV_IUUC_ODQ020 - Number of parallel requests set to zero, assuming default of 2 ?

  The SAP error message CNV_IUUC_ODQ020 indicates that the number of parallel requests for the data transfer process has been set to zero. This typically occurs in the context of data migration or data transfer scenarios, particularly when using the SAP Landscape Transformation (SLT) replication or other data migration tools.
  Cause:
  
  Configuration Issue: The error usually arises from a misconfiguration in the settings for parallel processing. If the system is set to allow zero parallel requests, it cannot process any data in parallel, leading to this error.
  System Limitations: There may be system limitations or restrictions that prevent the configuration of parallel requests.
  User Permissions: Insufficient permissions or roles assigned to the user executing the data transfer can also lead to this error.
  
  Solution:
  
  
  Adjust Configuration:
  
  Go to the relevant configuration settings in the SAP system where the parallel request settings are defined.
  Increase the number of parallel requests to a value greater than zero (e.g., set it to the default of 2 or higher if needed).
  This can typically be done in transaction codes like SLT Configuration or through the relevant customizing settings.
  
  
  
  Check System Parameters:
  
  Review the system parameters related to parallel processing. Ensure that there are no restrictions that would limit the number of parallel requests.
  
  
  
  User Roles and Permissions:
  
  Verify that the user executing the data transfer has the necessary permissions to modify the settings and execute parallel requests.
  
  
  
  Restart the Process:
  
  After making the necessary changes, restart the data transfer process to see if the error persists.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SLT (for Landscape Transformation) and SM37 (for monitoring jobs) to manage and monitor data transfer jobs.
  Documentation: Refer to SAP Help documentation for detailed guidance on configuring SLT and managing parallel requests.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  If the issue persists after following these steps, consider reaching out to SAP support for further assistance, as there may be underlying issues specific to your system configuration or environment.
