  SAP Error Message:
  W0136 Number range interval & already maintained for layout
  
  Cause:
  This warning message occurs when you try to create or assign a number range interval for a particular layout (or object) in SAP, but the number range interval you are attempting to maintain has already been assigned or maintained for that layout.
  In other words, the system detects that the number range interval you want to use is not unique for the given layout because it has been previously defined or assigned. Number ranges in SAP must be unique per object or layout to avoid conflicts in document numbering.
  
  Explanation:
  
  Number ranges are used in SAP to assign unique numbers to documents or objects.
  Each layout or object can have one or more number range intervals.
  When maintaining number ranges (via transaction SNRO, or specific customizing paths), you must ensure that intervals do not overlap or duplicate for the same layout.
  The warning W0136 indicates that the interval you are trying to maintain is already in use for the layout, so maintaining it again would cause duplication or overlap.
  
  
  Solution:
  
  
  Check Existing Number Ranges:
  
  Go to the transaction or customizing path where number ranges are maintained (e.g., SNRO, or IMG path for the specific module).
  Review the number range intervals already assigned to the layout.
  
  
  
  Avoid Duplicate Intervals:
  
  Do not create or assign a number range interval that overlaps or duplicates an existing interval for the same layout.
  If you need a new interval, create a new number range interval with a unique number range (start and end numbers) that does not overlap with existing intervals.
  
  
  
  Adjust or Delete Intervals if Necessary:
  
  If the existing intervals are incorrect or obsolete, consider deleting or adjusting them before creating new intervals.
  Be cautious when deleting intervals as it may affect existing documents.
  
  
  
  Use Correct Layout:
  
  Verify that you are maintaining the number range for the correct layout.
  Sometimes the error occurs because the layout code is incorrect or duplicated.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SNRO – Number Range Objects maintenance.
  Module-specific number range customizing (e.g., for SD, MM, FI).
  
  
  
  IMG Path Example:
  
  For Sales Documents: SPRO -> Sales and Distribution -> Basic Functions -> Number Ranges -> Define Number Ranges
  
  
  
  Notes:
  
  Number ranges must be unique and non-overlapping per object/layout.
  Overlapping number ranges can cause document number conflicts and inconsistencies.
  Always back up or document existing number ranges before making changes.
  
  
  
  
  Summary:
  
  Cause: Attempt to maintain a number range interval that already exists for the layout.
  Solution: Check existing intervals, avoid duplicates, create unique intervals, or adjust/delete existing ones.
  Related: Use SNRO or module-specific customizing to manage number ranges properly.
