• What is the cause and solution for SAP error message CZ100 - Enter consecutive number & only once ?

  The SAP error message CZ100 ("Enter consecutive number & only once") typically occurs in the context of creating or processing documents that require sequential numbering, such as purchase orders, sales orders, or other transactional documents. This error indicates that the system expects a consecutive number to be entered, but the number provided does not meet the criteria.
  Cause:
  
  Non-Consecutive Numbering: The number entered does not follow the expected sequence. For example, if the last used number was 1001, entering 1003 would trigger this error if 1002 was skipped.
  Duplicate Entry: The number has already been used in the system, and the system does not allow duplicate entries for that particular document type.
  Configuration Issues: The number range configuration in the system may not be set up correctly, leading to issues with how numbers are assigned or validated.
  
  Solution:
  
  Check Number Sequence: Ensure that the number you are trying to enter is the next in the sequence. If you skipped a number, you may need to enter the correct consecutive number.
  Review Existing Entries: Look for existing entries in the system to confirm that the number you are trying to use has not already been assigned.
  Adjust Number Range Configuration: If you have access to configuration settings, check the number range settings for the document type you are working with. Ensure that the number ranges are correctly defined and that they allow for the expected sequence of numbers.
  Use Automatic Number Assignment: If manual entry is causing issues, consider using the automatic number assignment feature provided by SAP, which can help avoid these errors.
  Consult Documentation or Support: If the issue persists, refer to SAP documentation or consult with your SAP support team for further assistance.
