• What is the cause and solution for SAP error message W4123 - &: & Material is used in inspection lots ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W4123 & : & Material is used in inspection lots
  
  Meaning / Cause:
  This warning message appears when you try to perform certain changes or deletions on a material that is currently referenced in one or more inspection lots in the Quality Management (QM) module.
  
  Inspection lots are created for quality inspection purposes and are linked to materials.
  If a material is involved in active or existing inspection lots, SAP prevents changes that could affect the integrity or traceability of quality data.
  The message indicates that the material you are trying to change or delete is still used in inspection lots, so the system restricts the operation to avoid inconsistencies.
  
  
  When does this occur?
  
  When attempting to delete or change a material master record that is linked to inspection lots.
  When trying to change certain fields in the material master that are relevant for QM or inspection processes.
  During material master data maintenance or deletion transactions (e.g., MM02, MM06).
  
  
  Solution / How to resolve:
  
  
  Check Inspection Lots:
  
  Use transaction QA33 (Display Inspection Lots) or QA32 (Change Inspection Lots) to find all inspection lots related to the material.
  Identify if there are any open or active inspection lots.
  
  
  
  Close or Delete Inspection Lots:
  
  If possible, complete or close the inspection lots.
  If inspection lots are no longer needed and can be deleted, use QA11 (Record Results) and QA12 (Usage Decision) to complete the inspection lot, or QA22 to delete it if allowed.
  
  
  
  Wait for Inspection Lots to be Completed:
  
  Sometimes, you must wait until all inspection lots are processed and closed before making changes to the material.
  
  
  
  Check Customizing Settings:
  
  In some cases, the system behavior can be influenced by customizing settings in QM.
  Consult with your QM or SAP Basis team if you believe the restriction is too strict or needs adjustment.
  
  
  
  Alternative Approach:
  
  If you cannot delete or change the material due to inspection lots, consider creating a new material with the desired attributes and phase out the old material after all inspection lots are closed.
  
  
  
  
  Additional Information:
  
  This message is a warning (W), not an error, so it may allow you to continue with caution depending on the operation.
  The placeholders & in the message are replaced by the material number and other relevant details during runtime.
  The message is part of the QM integration with MM to ensure data consistency and traceability in quality inspections.
  Always ensure that quality data integrity is maintained when modifying materials linked to inspection lots.
