• What is the cause and solution for SAP error message /SCWM/HU_WM155 - Mixed storage in HU (&1) for st. type &2 failed due to insp. ID check ?

  The SAP error message /SCWM/HU_WM155 indicates that there is an issue with mixed storage in Handling Units (HUs) due to an inspection ID check. This typically occurs in the context of Warehouse Management (WM) and Extended Warehouse Management (EWM) when trying to store different materials or batches in the same Handling Unit (HU) that are subject to inspection.
  Cause:
  
  Inspection ID Check: The error suggests that the system is enforcing an inspection ID check for the materials being stored in the same HU. This means that the materials or batches have different inspection requirements or statuses that do not allow them to be mixed.
  Storage Type Configuration: The storage type configuration may not allow mixed storage for the specific materials or batches due to their inspection status.
  Material Master Settings: The material master records may have settings that prevent mixed storage, such as different quality inspection settings or batch management settings.
  
  Solution:
  
  Review Inspection Settings: Check the inspection settings for the materials involved. Ensure that they are compatible for mixed storage. If necessary, adjust the inspection settings to allow for mixed storage.
  Storage Type Configuration: Review the configuration of the storage type in the Warehouse Management settings. Ensure that mixed storage is allowed for the specific storage type and that the inspection ID check is configured correctly.
  Handling Unit Management: If the materials cannot be mixed due to inspection requirements, consider creating separate HUs for each material or batch to comply with the inspection ID check.
  Material Master Review: Check the material master records for the involved materials. Ensure that the settings related to quality management and batch management are consistent and allow for mixed storage if that is desired.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific configuration settings related to mixed storage and inspection ID checks.
