• What is the cause and solution for SAP error message /SCWM/WB_CORE086 - Unit of measurement cannot be empty ?

  The SAP error message /SCWM/WB_CORE086: Unit of measurement cannot be empty typically occurs in the context of the Extended Warehouse Management (EWM) module when a user attempts to perform an action that requires a unit of measurement (UoM), but the system finds that the UoM field is empty.
  Cause:
  
  Missing UoM in Master Data: The material master data for the item being processed may not have a defined unit of measurement.
  Incorrect Configuration: The configuration settings for the warehouse or the material may not be set up correctly, leading to the absence of a UoM.
  Data Entry Error: During the creation or processing of a document (like a transfer order, inbound delivery, etc.), the user may have inadvertently left the UoM field blank.
  Integration Issues: If the data is being transferred from another system (like an ERP system), there may be issues with the data mapping or transfer that result in missing UoM information.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and verify that the unit of measurement is correctly defined for the relevant material.
  Ensure that the base unit of measure and any alternative units of measure are properly maintained.
  
  
  
  Review Document Entry:
  
  If the error occurs during document entry, ensure that all required fields, including the unit of measurement, are filled out correctly.
  If using a custom transaction or interface, check the logic to ensure that the UoM is being populated correctly.
  
  
  
  Configuration Check:
  
  Review the configuration settings in the EWM system to ensure that the warehouse and material settings are correctly defined.
  Check if there are any specific settings related to UoM that need to be adjusted.
  
  
  
  Data Transfer Validation:
  
  If the data is being imported or transferred from another system, validate the data mapping and ensure that the UoM is included in the data being sent to SAP.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific error message for any additional troubleshooting steps or known issues.
