• What is the cause and solution for SAP error message NJIT_MSG878 - Max. allowed length of generated number cannot exceed 20 characters ?

  The SAP error message NJIT_MSG878 indicates that a generated number exceeds the maximum allowed length of 20 characters. This error typically occurs in scenarios where a system is trying to generate a unique identifier, such as a document number, order number, or any other type of key that is subject to length restrictions.
  Cause:
  
  Configuration Settings: The system may be configured to generate numbers that exceed the maximum length allowed. This can happen if the number generation logic concatenates multiple fields or includes additional characters that push the total length beyond 20.
  Custom Code: If there is custom ABAP code or enhancements that generate numbers, they may not adhere to the length restrictions.
  Data Input: User input or data being processed may inadvertently lead to the generation of a longer identifier.
  
  Solution:
  
  Review Configuration: Check the configuration settings for number ranges or number generation logic in the relevant module (e.g., Sales and Distribution, Materials Management). Ensure that the maximum length is set correctly and that the generated numbers do not exceed this limit.
  Modify Custom Code: If there is custom code involved in number generation, review it to ensure that it adheres to the 20-character limit. You may need to truncate or modify the logic to ensure compliance.
  Adjust Input Data: If the error is caused by user input or data being processed, ensure that the data conforms to the expected formats and lengths.
  Testing: After making changes, conduct thorough testing to ensure that the issue is resolved and that no new issues arise from the changes made.
