SAP Error Message - Details

• Message type: E = Error

• Message class: WD - Workflow definition

• Message number: 490

• Message text: Problems caused by number range object '&'

What causes this issue?

The number range object used does not return any numbers. It is
therefore not possible to create any workflows.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the number range for workflows with <DS:TRAN.SNUM>transaction
SNUM</>. The interval <ZH>01</> is used for number assignment which is
exclusively internal and must not be marked as external. If such an
entry does not exist, insert this entry.

• What is the cause and solution for SAP error message WD490 - Problems caused by number range object '&' ?

  SAP Error Message:
  
  WD490 Problems caused by number range object '&'
  
  Cause:
  This error typically occurs when there is an issue related to the number range object used in Web Dynpro applications or other SAP components. The placeholder '&' in the message is replaced by the actual number range object name at runtime.
  Common causes include:
  
  The number range object is not properly defined or activated in the system.
  The number range interval is exhausted (no more numbers available).
  The number range object is not assigned or linked correctly to the application or business object.
  Authorization issues preventing access to the number range object.
  Inconsistent or corrupted number range intervals.
  
  
  Explanation:
  Number ranges in SAP are used to generate unique identifiers (e.g., document numbers, IDs). When a program tries to fetch the next number from a number range object and encounters a problem (like no available numbers or missing configuration), it raises this error.
  
  Solution:
  
  
  Check Number Range Object Configuration:
  
  Go to transaction SNRO (Number Range Objects).
  Enter the number range object name (replace '&' with the actual object name from the error).
  Verify that the number range intervals are defined and active.
  Check if the current number is within the defined intervals.
  
  
  
  Extend Number Range Intervals:
  
  If the number range is exhausted, create a new interval with a higher range.
  Make sure intervals do not overlap and are continuous.
  
  
  
  Assign Number Range Object Correctly:
  
  Ensure the number range object is correctly assigned to the application or business object.
  Check customizing or configuration settings where the number range object is linked.
  
  
  
  Check Authorizations:
  
  Verify that the user or process has the necessary authorizations to access and update the number range object.
  
  
  
  Consistency Check:
  
  Run consistency checks or use standard SAP reports to verify number range integrity.
  If inconsistencies are found, correct them or contact SAP support.
  
  
  
  Debugging:
  
  If the problem persists, debug the program to see exactly where and why the number range fetch fails.
  
  
  
  
  Related Information:
  
  Transaction SNRO: Manage number range objects.
  Transaction SNUM: Number range maintenance for specific objects.
  SAP Note references related to number range issues (search SAP Support Portal with the error message and number range object).
  Number ranges are critical in many SAP modules (FI, MM, SD, HR, etc.), so ensure cross-module consistency if applicable.
  Web Dynpro applications often use number ranges for unique IDs; check the component configuration if error occurs in Web Dynpro context.
  
  
  Summary:
  The error WD490 indicates a problem with a number range object, usually due to missing or exhausted intervals or configuration issues. The solution involves checking and maintaining the number range object via SNRO, ensuring intervals are defined and active, and verifying proper assignment and authorization.
  
  If you provide the actual number range object name or the context (module, transaction, or program), I can give more specific guidance.
