• What is the cause and solution for SAP error message W0135 - Number range & already exists. This cannot be used twice ?

  Certainly! Here's a detailed explanation of the SAP error message W0135: "Number range & already exists. This cannot be used twice":
  
  Error Message:
  W0135 - Number range & already exists. This cannot be used twice
  
  Cause:
  This warning message occurs when you try to create or define a number range interval in SAP that overlaps or duplicates an existing number range interval for the same object or number range object.
  In SAP, number ranges are used to assign unique numbers to documents, master data, or other objects. Each number range interval must be unique and non-overlapping within the same number range object.
  Common scenarios causing this error:
  
  Attempting to create a new number range interval with a number range ID that already exists.
  Defining a number range interval with a number range object and interval boundaries that overlap with an existing interval.
  Trying to assign the same number range interval to two different number range objects.
  
  
  Explanation:
  
  SAP enforces uniqueness of number range intervals to avoid conflicts in document numbering.
  If you try to create or maintain a number range interval that duplicates an existing one, SAP raises this warning to prevent inconsistent numbering.
  
  
  Solution:
  
  
  Check Existing Number Ranges:
  
  Go to transaction SNRO (Number Range Objects) or SNUM (Number Range Maintenance).
  Select the relevant number range object.
  Review the existing intervals and their number ranges.
  
  
  
  Avoid Overlapping Intervals:
  
  Ensure the new interval you want to create does not overlap with any existing intervals.
  Adjust the "From Number" and "To Number" fields so that the new interval is unique and does not conflict.
  
  
  
  Use a Different Number Range ID:
  
  If you are trying to create a number range with an ID that already exists, use a different ID.
  
  
  
  Delete or Adjust Existing Intervals (if appropriate):
  
  If an existing interval is no longer needed or was created by mistake, you may delete or adjust it to free up the number range.
  
  
  
  Check for Transport or Client-Specific Issues:
  
  Sometimes, number ranges are client-specific or transported between systems. Ensure that the number range intervals are consistent across clients and systems.
  
  
  
  
  Additional Information:
  
  
  Transaction Codes:
  
  SNRO - Number Range Objects maintenance.
  SNUM - Number Range Intervals maintenance.
  OBN2 - Number range intervals for FI documents.
  FBN1 - Number range intervals for FI documents (alternative).
  
  
  
  Number Range Objects:
  
  These are defined in SAP to control the numbering of various business objects (e.g., sales orders, purchase orders, invoices).
  Each object has one or more number range intervals assigned.
  
  
  
  Best Practices:
  
  Always plan number ranges carefully to avoid overlaps.
  Document number range intervals and their usage.
  Use separate number ranges for different document types or business areas if needed.
  
  
  
  
  Summary:
  
  
  
  Aspect
  Description

  Attempt to create a number range interval that duplicates or overlaps an existing interval.
  
  
  Effect
  SAP raises warning W0135 to prevent duplicate number ranges.
  
  
  Solution
  Check existing intervals, avoid overlaps, use unique intervals, and adjust or delete conflicts.
