• What is the cause and solution for SAP error message WR126 - Enter positive quantity ?

  SAP Error Message:
  
  WR126 - Enter positive quantity
  
  Cause:
  This error occurs when a quantity field in a transaction or data entry screen is left blank, zero, or contains a negative value where the system expects a positive quantity. SAP requires certain quantity fields (e.g., order quantity, delivery quantity, goods movement quantity) to be strictly positive numbers. Entering zero or negative values violates this rule, triggering the error.
  
  Solution:
  
  Enter a positive quantity: Make sure to input a quantity greater than zero in the relevant field.
  Check the field: Identify which quantity field is causing the error and correct the value.
  Data validation: If the quantity is coming from an interface or upload, verify the source data to ensure no zero or negative quantities are passed.
  Customizing check: In rare cases, if zero or negative quantities are valid for your business process, check with your SAP functional consultant if the validation logic can be adjusted (though generally not recommended).
  
  
  Related Information:
