  SAP Error Message:
  W0155 - External number range '&' does not exist
  
  
  Cause:
  This warning message occurs when an external number range is expected or specified in a transaction or program, but the system cannot find or identify the external number range with the given identifier (represented by '&' as a placeholder for the actual number range object).
  In SAP, number ranges are used to assign unique document or object numbers. Number ranges can be internal (system-assigned) or external (user-assigned). When an external number range is specified but not defined or missing in the system, this error appears.
  Common causes include:
  
  The number range object or interval has not been created or maintained in the system.
  The number range object exists but does not have an external number range interval defined.
  The program or transaction is trying to use an external number range that is not assigned or activated.
