  Error Message
  W5090: Enter a unit of measure for service &
  
  Cause
  This warning message appears when you are trying to enter or process a service item in a document (such as a sales order, purchase order, or service entry sheet) without specifying a unit of measure (UoM) for the service.
  
  In SAP, every material or service item requires a unit of measure to quantify the amount of goods or services.
  For service items, the unit of measure could be hours, days, pieces, or any other relevant unit defined in the system.
  If the unit of measure field is left blank or not maintained, SAP triggers this warning to ensure that the quantity of the service is properly defined.
  
  
  Solution
  To resolve this warning:
  
  
  Enter the Unit of Measure:
  
  When creating or editing the service item, make sure to enter a valid unit of measure in the "Unit" field.
  The unit of measure should be consistent with the service being provided (e.g., H for hours, DY for days).
  
  
  
  Check Master Data:
  
  Verify that the service master record (if applicable) has a default unit of measure maintained.
  If the service is created as a material master of type "Service" (material type 'D'), ensure the base unit of measure is correctly set.
  
  
  
  Check Document Type and Item Category:
  
  Some item categories or document types may require a unit of measure explicitly.
  Ensure that the item category assigned to the service item allows or requires a unit of measure.
  
  
  
  Configuration Check:
  
  In some cases, the system might be customized to require a unit of measure for services.
  Check the configuration in IMG under Sales and Distribution or Materials Management to confirm the settings for service items.
  
  
  
  
  Additional Information
  
  Message Class: W5 (Warning)
  Transaction Context: This message commonly appears in transactions like VA01 (Create Sales Order), ME21N (Create Purchase Order), or ML81N (Service Entry Sheet).
  Impact: Since this is a warning (not an error), you may be able to proceed without entering the unit of measure, but it is strongly recommended to enter it to avoid inconsistencies in quantity and billing.
  Related Fields: 
  
  Item Category (e.g., D for service items)
