How To Fix NR107 - The calculated number length without prefix & is 0

SAP Error Message - Details

• Message type: E = Error

• Message class: NR - Number ranges

• Message number: 107

• Message text: The calculated number length without prefix & is 0

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

You are using a number range object with prefix. When editing intervals,
the length of the prefix is subtracted from the defined number length.
The calculated length must be at least 1 before an interval can be
created.

• What is the cause and solution for SAP error message NR107 - The calculated number length without prefix & is 0 ?

  The SAP error message NR107, which states "The calculated number length without prefix & is 0," typically occurs in the context of number range management. This error indicates that the system is unable to determine a valid number for a specific number range because the calculated length of the number is zero. This can happen for various reasons, often related to the configuration of number ranges.
  Causes:
  
  Incorrect Number Range Configuration: The number range object may not be properly configured, leading to a situation where the system cannot derive a valid number.
  Missing Number Range Intervals: The number range intervals may not be defined or may have been deleted, resulting in no available numbers.
  Prefix Issues: If a prefix is defined for the number range but is not correctly set up, it can lead to a situation where the system cannot calculate the number length.
  Data Type Mismatch: The data type of the number range may not match the expected format, causing issues in number generation.
  
  Solutions:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Find the relevant number range object and check its configuration.
  Ensure that the number range intervals are correctly defined and active.
  
  
  
  Define or Adjust Number Range Intervals:
  
  If the intervals are missing, create new intervals for the number range.
  Ensure that the intervals cover the required range and are not overlapping with other intervals.
  
  
  
  Review Prefix Settings:
  
  If a prefix is used, verify that it is correctly defined in the number range object.
  Ensure that the prefix does not lead to a zero-length calculation.
  
  
  
  Check Data Types:
  
  Ensure that the data type of the number range is appropriate for the values being generated.
  If necessary, adjust the data type settings to match the expected format.
  
  
  
  Testing:
  
  After making changes, test the number range generation to ensure that the error does not reoccur.
