• What is the cause and solution for SAP error message /SCWM/UI_PACKING185 - Exact conversions is not possible. Enter quantity in Base unit of measure ?

  The SAP error message /SCWM/UI_PACKING185 indicates that there is an issue with the quantity being entered during the packing process in the SAP Extended Warehouse Management (EWM) system. The message specifically states that "Exact conversions are not possible" and suggests that the quantity should be entered in the base unit of measure.
  Cause:
  This error typically occurs due to one of the following reasons:
  
  
  Unit of Measure (UoM) Conversion Issues: The quantity you are trying to enter is in a different unit of measure that cannot be exactly converted to the base unit of measure defined for the material. For example, if the base unit of measure is "EA" (each) and you are trying to enter a quantity in "KG" (kilograms) without a defined conversion factor, the system will not allow it.
  
  
  Missing Conversion Factors: The material master may not have the necessary conversion factors defined for the different units of measure. If the system cannot determine how to convert the entered quantity to the base unit of measure, it will throw this error.
  
  
  Incorrect Quantity Entry: The quantity entered may not be valid or may not correspond to the allowed units of measure for the material.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the units of measure tab to ensure that the base unit of measure is correctly defined and that the necessary conversion factors for other units of measure are set up.
  
  
  
  Enter Quantity in Base Unit of Measure:
  
  When prompted for a quantity, ensure that you are entering it in the base unit of measure. If the base unit of measure is "EA," enter the quantity in pieces rather than in weight or volume.
  
  
  
  Review UoM Settings:
  
  Ensure that the unit of measure settings in the system are correctly configured. This includes checking the conversion factors and ensuring that they are appropriate for the material.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct units of measure or conversion factors, consult the relevant SAP documentation or your organization's SAP support team for guidance.
  
  
  
  Testing:
  
  After making any changes, test the packing process again to ensure that the error does not reoccur.

  User Training: Ensure that users involved in the packing process are trained on how to enter quantities correctly and understand the importance of using the base unit of measure.
  
  
  By following these steps, you should be able to resolve the error and continue with the packing process in SAP EWM.
