• What is the cause and solution for SAP error message CNV20201429 - Max. number (&) reached for logging of objects without number range ?

  The SAP error message CNV20201429 indicates that the maximum number of objects without a number range has been reached during a data migration or conversion process. This error typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer processes.
  Cause:
  The error is caused by the system reaching a predefined limit for logging objects that do not have a number range assigned. This can happen when:
  
  A large number of objects are being processed without a proper number range.
  The configuration settings for logging or the number of allowed entries for objects without a number range are not sufficient for the volume of data being migrated.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Increase the Limit: 
  
  Check the configuration settings related to the logging of objects without a number range. You may need to increase the maximum number of allowed entries. This can typically be done in the customizing settings of the relevant migration tool or by consulting the SAP documentation for the specific migration process you are using.
  
  
  
  Assign Number Ranges:
  
  If possible, assign number ranges to the objects being processed. This can help in managing the logging more effectively and prevent hitting the limit.
  
  
  
  Review Migration Objects:
  
  Analyze the objects being migrated to see if there are any that can be excluded or processed in smaller batches. This can help in reducing the overall load and prevent the error from occurring.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest support packages and notes. Sometimes, SAP releases notes that address specific issues related to data migration.
