• What is the cause and solution for SAP error message WXP353 - Also enter the issue figure for "Calculation of day's supply" ?

  Certainly! Here's a detailed explanation for the SAP error message WXP353:
  
  SAP Message: WXP353 - Also enter the issue figure for "Calculation of day's supply"
  
  Cause:
  This warning message appears in SAP when you are maintaining or processing a material master record (typically in the MRP 2 view) or during planning activities, and the system expects an issue figure (also called daily consumption or daily usage) to be entered for the calculation of the day's supply.
  
  The day's supply is a key parameter used in material requirements planning (MRP) to determine how many days the current stock will last based on the daily consumption.
  If the issue figure (daily consumption) is missing or zero, SAP cannot calculate the day's supply.
  This usually happens when the Issue for Calculation of Day's Supply indicator is set, but the corresponding issue figure is not maintained.
  
  
  Where does this happen?
  
  In the Material Master under MRP 2 view:
  
  Field: Issue for Calculation of Day's Supply (checkbox)
  Field: Issue Figure (daily consumption quantity)
  
  
  During MRP runs or consumption-based planning, if the system needs to calculate the day's supply but the issue figure is missing, this warning is triggered.
  
  
  Solution:
  
  
  Enter the Issue Figure:
  
  Go to the material master record (transaction MM02).
  Navigate to the MRP 2 view.
  Check if the Issue for Calculation of Day's Supply checkbox is selected.
  If yes, enter a valid Issue Figure (daily consumption quantity) in the corresponding field.
  Save the material master.
  
  
  
  If you do not want to use the day's supply calculation:
  
  Uncheck the Issue for Calculation of Day's Supply checkbox.
  This will prevent the system from expecting an issue figure.
  
  
  
  Review Consumption Data:
  
  If you are unsure about the daily consumption, analyze historical consumption data or use forecasted values to estimate the issue figure.
  
  
  
  Check Customizing Settings:
  
  Sometimes, the system settings or user exits might enforce this check.
  Review MRP parameters and user exits if the warning persists despite correct data.
  
  
  
  
  Additional Information:
  
  Day's Supply Calculation is used in consumption-based planning to help determine reorder points and safety stock levels.
  The Issue Figure represents the average daily consumption quantity.
  This warning is not an error; it is a warning (message class WXP, message number 353), so the system allows you to continue but advises you to maintain the data for accurate planning.
  Ignoring this warning may lead to inaccurate MRP results or stock shortages.
