What causes this issue?

The retail price refers to the sales unit of measure with which the
material is sold to consumers. The base unit of measure is the unit of
measure with which the material is valuated in inventory management.
If these units of measure are different, the retail price is converted
from the sales unit of measure to the base unit of measure for

  Error Message
  WR092: Sales unit and base unit of measure do not match
  
  Cause
  This error occurs when there is a mismatch or inconsistency between the Sales Unit and the Base Unit of Measure for a material in SAP. Specifically:
  
  The Sales Unit (used in sales documents) and the Base Unit of Measure (used as the standard unit for inventory management) are not compatible or correctly maintained.
  The system expects the sales unit to be either the same as the base unit or a valid alternative unit of measure that can be converted to the base unit using a defined conversion factor.
  If the sales unit is not maintained in the material master or the conversion factor between the sales unit and base unit is missing or incorrect, this error can occur.
  
  
  Where It Occurs
  
  During sales order creation or processing (transaction VA01, VA02, VA03).
  When the system tries to validate the unit of measure consistency for the material in sales documents.
  
  
  Solution
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Check the Base Unit of Measure on the Basic Data 1 tab.
  Check the Sales Unit in the Sales: Sales Org. 1 or Sales: General/Plant Data tab.
  
  
  
  Maintain Alternative Units of Measure:
  
  Go to transaction CUNI or use the material master (MM02) to maintain alternative units of measure.
  Ensure that the sales unit is defined as an alternative unit of measure for the material.
  Maintain the correct conversion factor between the sales unit and the base unit of measure.
  
  
  
  Maintain Conversion Factors:
  
  In the material master (MM02), under the Units of Measure view, maintain the conversion factor between the sales unit and the base unit.
  For example, if the base unit is "PC" (pieces) and the sales unit is "BOX", define how many pieces are in one box.
  
  
  
  Consistency Check:
  
  Ensure that the sales unit is valid and consistent with the base unit.
  If the sales unit is not supposed to be different, correct it to match the base unit.
  
  
  
  Check Customizing (if applicable):
  
  Sometimes, unit of measure groups or unit of measure conversions are controlled via customizing.
  Check in SPRO under Logistics - General > Units of Measure > Check Units of Measure for any restrictions or settings.
  
  
  
  
  Additional Information
  
  Base Unit of Measure: The unit in which stock quantities are managed in inventory.
  Sales Unit: The unit in which the material is sold to customers.
  Alternative Units of Measure: Units other than the base unit that can be used for sales, purchasing, or production, provided conversion factors are maintained.
  Conversion Factor: The ratio used to convert quantities from one unit of measure to another.
