• What is the cause and solution for SAP error message NR587 - Entered number level is less than the previous number level & & & & ?

  The SAP error message NR587 ("Entered number level is less than the previous number level") typically occurs in the context of number range management, particularly when dealing with number ranges for documents, invoices, or other entities that require sequential numbering.
  Cause:
  This error arises when you attempt to enter a number that is lower than the last used number in the sequence for a specific number range. In SAP, number ranges are defined to ensure that each document or entity has a unique identifier, and they must follow a sequential order. If you try to assign a number that is less than the last number used, SAP will throw this error to maintain the integrity of the numbering system.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Last Used Number:
  
  Go to the transaction code SNRO (Number Range Objects) and find the relevant number range object.
  Check the last number that was used in the number range. This will give you an idea of what the current maximum number is.
  
  
  
  Use a Valid Number:
  
  Ensure that the number you are trying to enter is greater than the last used number. If you need to enter a new number, it should be higher than the last used number.
  
  
  
  Adjust Number Range Settings:
  
  If you need to reset or adjust the number range, you can do this in the number range object settings. However, be cautious with this approach as it can lead to gaps or duplicates if not managed properly.
  
  
  
  Consult with Your SAP Administrator:
  
  If you are unsure about how to proceed or if you need to change the number range settings, consult with your SAP administrator or a functional consultant who can provide guidance based on your organization's policies.
  
  
  
  Review Custom Code:
  
  If this error is occurring in a custom program or transaction, review the code to ensure that it is correctly handling number assignments and not inadvertently trying to assign a lower number.
