• What is the cause and solution for SAP error message W5091 - Line with quantity/unit of measure not possible without service ?

  SAP Error Message:
  
  W5091 - Line with quantity/unit of measure not possible without service
  
  Cause:
  This warning message occurs in SAP Sales and Distribution (SD) when you try to enter a line item with a quantity and unit of measure (UoM) but the item category or material type is configured as a service or the system expects a service item. In SAP, service items typically do not have a quantity or unit of measure in the same way as tangible goods do. If you enter a quantity/UoM for a service item or a line item that is not configured to handle quantity/UoM, the system issues this warning.
  In other words, the system expects that if you enter a quantity and unit of measure, the item must be a material (goods), not a service. Conversely, if the item is a service, quantity/UoM should not be entered or is not applicable.
  
  When does it occur?
  
  When creating or changing sales documents (e.g., sales orders, quotations).
  When the item category is set to a service type but quantity/UoM is entered.
  When the material master or item category settings do not allow quantity/UoM for the item.
  
  
  Solution:
  
  
  Check Item Category Configuration:
  
  Verify the item category assigned to the line item.
  Ensure that the item category is correctly set for service or material.
  For service items, the item category should be configured to not require quantity/UoM or handle it appropriately.
  
  
  
  Check Material Master Data:
  
  Confirm if the material is defined as a service or a material.
  For service materials, quantity/UoM might not be applicable or should be handled differently.
  
  
  
  Adjust Quantity/UoM Entry:
  
  If the item is a service, avoid entering quantity and unit of measure.
  If quantity/UoM is necessary, ensure the item is treated as a material, not a service.
  
  
  
  Item Category Determination:
  
  Review the item category determination procedure to ensure correct item category is assigned based on sales document type, material type, and usage.
  
  
  
  Customizing Settings:
  
  In SPRO, check the settings under:
  Sales and Distribution -> Sales -> Sales Documents -> Sales Document Item -> Define Item Categories
  Adjust the settings related to quantity and unit of measure for the relevant item categories.
  
  
  
  
  Additional Information:
  
  This message is a warning (W), so it may not block document saving but indicates a potential inconsistency.
  The message helps maintain data integrity by ensuring that service items are not incorrectly processed as goods with quantities.
  If your business process requires quantity for services (e.g., hours worked), consider using a service item category that supports quantity and UoM or use a different approach like service confirmations or time sheets.
  
  
  Summary:
