How To Fix 06480 - Order unit & not convertible into unit & of requisition

SAP Error Message - Details

• Message type: E = Error

• Message class: 06 -

• Message number: 480

• Message text: Order unit & not convertible into unit & of requisition

What causes this issue?

You have changed the order unit for an item that references a purchase
requisition. The system cannot convert the order unit into the unit of
the requisition (because neither unit has a dimension for example). The
system will therefore convert using the factor 1.

How to fix this error?

The ordered quantity in the purchase requisition will be updated in the
amount of the PO quantity. In this case, too, conversion will be carried
out using the factor 1. You may have to manually flag the requisition as
closed (by deleting it).
&EXAMPLES&
You have a purchase requisition for 100 pcs. In the PO, you change the
order unit to "case". You order 10 cases from the supplier (each case
contains 10 pcs.). However, the ordered quantity in the purchase
requisition is only increased by 10 pcs. In this instance, a quantity of
90 pcs. would remain open.

• What is the cause and solution for SAP error message 06480 - Order unit & not convertible into unit & of requisition ?

  The SAP error message "06480 Order unit & not convertible into unit & of requisition" typically occurs when there is a mismatch between the order unit of a purchase order or production order and the unit of measure (UoM) specified in the requisition or material master. This can happen in various scenarios, such as when creating purchase orders, production orders, or stock transfer orders.
  Cause:
  
  Unit of Measure (UoM) Mismatch: The order unit defined in the order does not match the unit of measure defined in the material master or the requisition.
  Conversion Factor Issues: There may be no conversion factor defined between the two units of measure, or the conversion factor may not be valid.
  Material Master Settings: The material master may not have the correct UoM settings, or the UoM may not be maintained properly.
  Configuration Issues: There may be configuration issues in the system related to UoM settings.
  
  Solution:
  
  
  Check Material Master: 
  
  Go to the material master (transaction code MM03) and check the UoM settings. Ensure that the order unit and the requisition unit are correctly defined and that a conversion factor exists.
  
  
  
  Review Purchase Order/Production Order:
  
  Check the purchase order or production order to ensure that the order unit is correctly specified. If necessary, change the order unit to match the requisition unit.
  
  
  
  Define Conversion Factors:
  
  If there is no conversion factor defined, you can define it in the material master under the "Units of Measure" view. Ensure that the conversion factor is valid and correctly set up.
  
  
  
  Check Configuration:
  
  If the issue persists, check the configuration settings in the SAP system related to units of measure. This may require assistance from a functional consultant or someone with configuration access.
  
  
  
  Use Transaction Codes:
  
  Use transaction codes like ME21N (Create Purchase Order) or CO01 (Create Production Order) to review and adjust the order details.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on handling UoM issues.

  Conversion Factors: These are used to convert quantities from one unit of measure to another, allowing for flexibility in how materials are ordered and managed.
  
  If the problem continues after checking these areas, it may be necessary to involve your SAP support team or a consultant for further investigation.
