  The SAP error message WOG020 indicates an issue related to rounding in a collective purchase order. This error typically arises when the quantity of a material being ordered does not align with the defined order unit, leading to discrepancies in the total quantity that can be processed.
  Cause:
  
  Rounding Issues: The quantity specified in the purchase order may not be a multiple of the order unit defined for the material. For example, if the order unit is in packs of 10, and the user tries to order 15, the system may not be able to process this correctly.

  Solution:
  
  Adjust the Order Quantity: Ensure that the quantity being ordered is a multiple of the order unit. For example, if the order unit is 10, adjust the order quantity to 10, 20, 30, etc.
