  Cause:
  
  
  Missing Extension UoM: The primary cause of this error is that the system cannot find the required extension unit of measure for the material in question. This can happen if:
  
  The extension UoM has not been defined in the material master.
  The UoM is not properly maintained in the relevant configuration settings.
  There is a mismatch between the UoM used in the sales document and the UoM defined in the material master.
  
  
  
  Configuration Issues: There may be issues in the configuration of the unit of measure settings in the SAP system, such as missing entries in the relevant tables.
  
  
  Solution:
  To resolve the VYSC033 error, you can follow these steps:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" and "Sales Org. Data" views to ensure that the extension unit of measure is defined correctly.
  If it is missing, you may need to add the appropriate extension UoM.
  
  
  
  Maintain Unit of Measure:
  
  Use transaction code CUNI to access the unit of measure conversion settings.
  Ensure that the extension UoM is defined and that the conversion factors between the base UoM and the extension UoM are correctly maintained.
  
  
  
  Check Sales Document:
  
  Review the sales document (e.g., sales order, quotation) to ensure that the UoM used is valid and corresponds to the UoM defined in the material master.
  
  
  
  Configuration Settings:
  
  If you have access to configuration settings, check the settings for units of measure in the relevant customizing areas (e.g., Sales and Distribution > Basic Functions > Pricing > Pricing Control > Define Units of Measure).
