    Error Message

    WTY20001: Each master warranty can be assigned to an object only once


    Cause

    This error occurs when you try to assign the same master warranty more than once to the same object (equipment, functional location, or other technical object) in SAP.

    • In SAP Warranty Management, a master warranty defines the warranty conditions and is linked to objects.
    • The system enforces a rule that a particular master warranty can only be assigned once to a given object.
    • Attempting to assign the same warranty multiple times to the same object violates this rule, triggering the error.

    When does it typically occur?

    • During warranty assignment in transaction codes like IW31/IW32 (for service orders), IE01/IE02 (equipment master), or warranty-specific transactions.
    • When trying to add a warranty manually or via a program to an object that already has that warranty assigned.
    • During data migration or mass updates where duplicate warranty assignments might be attempted.

    Solution

    1. Check Existing Warranty Assignments:

      • Verify if the master warranty is already assigned to the object.
      • Use transaction IE03 (Display Equipment) or IL03 (Display Functional Location) and check the warranty tab or related warranty assignments.
      • Alternatively, use warranty-specific reports or tables (e.g., IWBW table stores warranty master data assignments).
    2. Avoid Duplicate Assignment:

      • If the warranty is already assigned, do not assign it again.
      • If you need to update warranty conditions, modify the existing assignment instead of creating a new one.
    3. Correct Data in Mass Uploads:

      • If the error occurs during data migration or mass upload, cleanse the data to remove duplicate warranty assignments for the same object.
    4. Check Custom Code or Enhancements:

      • If custom programs or user exits are assigning warranties, ensure they check for existing assignments before creating new ones.

    Related Information

    • Master Warranty: Defines warranty terms, conditions, and validity.

      • IL01/IL02/IL03: Create/Change/Display Functional Location.
      • IW31/IW32: Create/Change Service Order (where warranty can be assigned).
    • SAP Notes: Check for any SAP Notes related to warranty assignment issues if the problem persists.

    Summary
