  • What is the cause and solution for SAP error message WTY20005 - Each warranty type can only be assigned to an object once ?

    SAP Error Message:
    WTY20005 – "Each warranty type can only be assigned to an object once"


    Cause:

    This error occurs when you try to assign the same warranty type multiple times to the same object (e.g., equipment, material, or service object) in SAP. The system enforces a rule that each warranty type must be unique per object to avoid duplication and inconsistencies in warranty management.

    For example, if you have already assigned Warranty Type "A" to Equipment "1000", trying to assign Warranty Type "A" again to the same equipment will trigger this error.


    Solution:

    • Check existing warranty assignments:
      Review the warranty types already assigned to the object to ensure you are not duplicating an existing warranty type.

    • Remove or modify duplicates:
      If a duplicate warranty type exists, either remove the redundant assignment or change the warranty type to a different one that is not yet assigned to the object.

    • Use unique warranty types per object:
      Ensure that each warranty type is assigned only once per object. If multiple warranties are needed, use different warranty types.

    • Data correction:
      If the error is due to inconsistent or incorrect data, correct the data in the warranty master or equipment master records.


    Related Information:

    • Warranty Types:
      Warranty types define the kind of warranty (e.g., manufacturer warranty, extended warranty) and are configured in SAP under warranty management.

    • Warranty Assignment:
      Warranty types are assigned to objects such as equipment or materials in transactions like IW32 (Change Order), IE02 (Change Equipment), or through warranty master data maintenance.

    • Configuration:
      Warranty types and their assignment rules are maintained in IMG under:
      Logistics - General > Warranty Management > Warranty Types

    • Transaction Codes:

      • IE02 – Change Equipment
      • IW32 – Change Order
      • WTY1 – Warranty Master Data Maintenance (depending on system version)
    • SAP Notes:
      Check SAP Notes related to warranty management for any patches or updates if this error occurs unexpectedly.


    Summary:

    WTY20005 is a validation error preventing duplicate warranty type assignments to the same object. To resolve it, ensure each warranty type is assigned only once per object by reviewing and correcting warranty assignments.
