&Diagnose&
For SAP S/4HANA Cloud, you can only specify a maximum of 80% of all
available background jobs for each migration object to transfer data.
This restriction is due to performance considerations. If you are
transferring multiple objects in parallel it is important to note that
the background jobs will queue up, which can negatively impact the
performance of the system.

• What is the cause and solution for SAP error message CNV_DMC_WDA118 - Do not specify more than &1 jobs to transfer data ?

  The SAP error message CNV_DMC_WDA118 indicates that you are trying to specify more jobs for data transfer than the system allows. This error typically occurs in the context of data migration or data transfer processes, particularly when using the SAP Data Migration Cockpit or similar tools.
  Cause:
  The error is triggered when the number of jobs specified for data transfer exceeds the maximum limit set by the system. This limit is in place to ensure optimal performance and resource management during data migration processes. 
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Reduce the Number of Jobs: Review the number of jobs you are trying to specify for the data transfer. Ensure that you do not exceed the allowed limit. If you are trying to run multiple jobs simultaneously, consider reducing the number to comply with the system's constraints.
  
  
  Check Configuration Settings: Sometimes, the maximum number of jobs allowed can be configured in the system settings. Check if there are any configuration parameters that can be adjusted to allow for more jobs, but be cautious as increasing this limit may impact system performance.
  
  
  Batch Processing: If you have a large volume of data to transfer, consider breaking it down into smaller batches. This way, you can run multiple smaller jobs sequentially rather than trying to run too many jobs at once.
  
  
  Consult Documentation: Refer to the official SAP documentation or notes related to the specific data migration tool you are using. There may be additional guidelines or best practices that can help you manage job specifications effectively.
  
  
  Contact SAP Support: If you are unable to resolve the issue through the above steps, consider reaching out to SAP support for assistance. They may provide insights specific to your system configuration or version.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this error or provide additional context.
  Performance Considerations: Be aware that running too many jobs simultaneously can lead to performance degradation, so always consider the overall system load and performance when planning data transfers.
  Monitoring Tools: Utilize SAP monitoring tools to keep track of job performance and system resource usage during data migration activities.
  
  By following these steps, you should be able to address the CNV_DMC_WDA118 error and proceed with your data transfer tasks effectively.
