  The SAP error message RSM820 indicates that there is an issue with the naming convention of customer numbers in the system. Specifically, it states that object names (in this case, customer numbers) cannot start with a '0' in the defined customer name range. This is a common validation rule in SAP to ensure that customer numbers are unique and follow a specific format.
  Cause:
  The error typically occurs when:
  
  A user attempts to create or modify a customer number that begins with a '0'.
