• What is the cause and solution for SAP error message IUID086 - Using existing UII (&1&2) from OBJK instead of generated UII (&3&4) ?

  The SAP error message IUID086 indicates that the system is using an existing Unique Item Identifier (UII) from an object (OBJK) instead of generating a new UII. This typically occurs in the context of managing unique identifiers for serialized or tracked items in SAP, particularly in industries like manufacturing or logistics where tracking individual items is crucial.
  Cause:
  
  Existing UII Conflict: The system has detected that there is already an existing UII associated with the object in question. This can happen if the item has already been assigned a UII in a previous transaction or if there is a duplicate entry.
  Configuration Settings: The system may be configured to prefer existing UIIs over generating new ones, which can be a part of the business process.
  Data Integrity Issues: There may be issues with data integrity, such as incorrect or incomplete data entries that lead the system to revert to an existing UII.
  
  Solution:
  
  Review Existing UIIs: Check the existing UIIs associated with the object to ensure they are correct and valid. You can do this by using transaction codes like IQ01 (Create Equipment) or IQ02 (Change Equipment) to view the details.
  Check Configuration: Review the configuration settings in the system to determine if there are settings that dictate the use of existing UIIs. This may involve checking the settings in the relevant modules (like Logistics or Plant Maintenance).
  Data Cleanup: If there are data integrity issues, perform a cleanup of the data to ensure that there are no duplicates or incorrect entries that could be causing the conflict.
  Manual Override: If necessary, you may need to manually assign a new UII if the business process allows for it. This can usually be done through the relevant transaction codes or through a custom program if needed.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling UIIs in your version of SAP, as there may be version-specific nuances.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as IQ01, IQ02, IQ03 (Display Equipment), and others related to the management of serialized items.
  SAP Notes: Check SAP Notes for any known issues or patches related to UII handling that may provide additional context or solutions.
  User Exits and BAdIs: If your organization has custom logic implemented, check for any user exits or Business Add-Ins (BAdIs) that might affect UII generation and assignment.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a technical consultant who can provide deeper insights into the specific configuration and data setup in your SAP environment.
