  Cause:
  
  Average Price Calculation: In SAP, average prices are calculated based on a quantity base of 1. This means that when you are dealing with average price materials, the system expects the quantity to be in whole units (1, 2, 3, etc.) rather than fractions or other values.

  Material Master Settings: The material master record may have settings that enforce average pricing, and if the transaction does not comply with these settings, the error will occur.
  
  Solution:
  
  Check Quantity: Ensure that the quantity you are trying to post is a whole number. If you are entering a fractional quantity, adjust it to a whole number.
  Review Material Master: Check the material master record for the item you are trying to post. Ensure that the pricing method is set correctly and that it is compatible with the transaction you are attempting.
  Transaction Type: Verify that the transaction type you are using is appropriate for average price materials. Some transactions may not support average pricing.
  Consult Documentation: If you are unsure about the settings or the transaction, consult SAP documentation or your organization's SAP support team for guidance on how to handle average price materials.
