Smart SAP Assistant

• What is the cause and solution for SAP error message W0156 - Internal number range '&' does not exist ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W0156 Internal number range '&' does not exist
  
  Cause:
  This warning message occurs when the system tries to assign or use an internal number from a number range that has not been defined or does not exist in the system. In SAP, many objects (documents, master data, etc.) use internal number ranges to generate unique identifiers automatically. If the number range object or interval is missing or incorrectly configured, the system cannot generate the number, leading to this error.
  The placeholder '&' in the message is replaced by the actual number range object name when the message is displayed.
  
  Common Scenarios:
  
  Number range object has not been created or assigned.
  Number range intervals have not been maintained or are missing.
  The number range object is assigned to a transaction or document type but not properly configured.
  Custom developments or enhancements trying to use a number range object that does not exist.
  
  
  Solution:
  
  
  Check Number Range Object:
  
  Go to transaction SNRO (Number Range Objects).
  Enter the number range object name (the one shown in the message).
  Verify if the number range object exists.
  
  
  
  Maintain Number Range Intervals:
  
  In SNRO, select the number range object.
  Click on Intervals.
  Check if there is at least one valid number range interval defined.
  If not, create a new interval with appropriate number ranges.
  
  
  
  Assign Number Range Object:
  
  For certain applications, number range objects must be assigned to document types or other entities.
  For example, in FI documents, check transaction FBN1.
  For sales documents, check VOV8 or relevant customizing.
  
  
  
  Check Custom Code:
  
  If this error occurs in a custom program or enhancement, verify that the number range object used in the code exists and is properly maintained.
  
  
  
  Transport and System Consistency:
  
  Sometimes, number range objects or intervals are missing due to incomplete transports between systems.
  Ensure that the number range object and intervals are transported correctly.

  Summary:
  The error W0156 Internal number range '&' does not exist indicates a missing or incorrectly configured number range object. To resolve it, verify and maintain the number range object and intervals in transaction SNRO, ensure proper assignment, and check any custom code or transports related to number ranges.
