• What is the cause and solution for SAP error message WH045 - Value & in the quantity field is not numerical ?

  SAP Error Message:
  
  WH045 - Value & in the quantity field is not numerical
  
  Cause:
  This error occurs when a non-numeric character or an invalid value is entered in a quantity field in SAP, which expects a strictly numerical input. The system tries to interpret the input as a number but encounters characters that are not digits, decimal separators, or valid numeric symbols.
  Common scenarios include:  
  
  Entering alphabetic characters or special symbols (e.g., letters, &, %, etc.) in quantity fields.  
  Copy-pasting data from external sources that include hidden or invalid characters.  
  Using incorrect decimal separators (e.g., comma vs. period) depending on user locale settings.  
  Input fields that are formatted to accept only numbers but receive invalid input due to user error or interface issues.
  
  
  Solution:
  
  
  Check the Input:
  
  Verify that the quantity field contains only valid numeric characters. Remove any letters, special characters, or spaces.
  
  
  Correct Decimal Separators:
  
  Ensure that the decimal separator used matches the user’s locale settings in SAP (e.g., comma or period). You can check/change this in user parameters or system settings.
  
  
  Re-enter the Quantity:
  
  Manually retype the quantity value to avoid hidden or non-printable characters.
  
  
  Validate Data Source:
  
  If data is being uploaded or copied from external files (Excel, CSV), ensure the data is clean and formatted correctly before import.
  
  
  Check Field Settings:
  
  If you are a developer or consultant, verify that the field data type is correctly defined as numeric in the screen or program.
  
  
  SAP Notes and Support:
  
  If the problem persists despite correct input, check for relevant SAP Notes or patches that might address input validation issues in your SAP version.
  
  
  
  Related Information:
  
  This error is common in Warehouse Management (WM) or Inventory Management (IM) transactions where quantities are entered (e.g., transfer postings, goods movements).  
  The message number WH045 indicates it is related to Warehouse Management module.  
  User locale and decimal notation settings can be checked via transaction SU3 (Maintain User Profile) under the Defaults tab.  
  Always ensure that input fields are used as intended and that any custom enhancements or user exits do not interfere with standard input validation.
  
  
  Summary:
  
  The WH045 error is caused by entering non-numeric characters in a quantity field. The solution is to ensure only valid numeric values are entered, respecting the correct decimal separator and cleaning any copied data before input.
