• What is the cause and solution for SAP error message CN004 - Enter a numeric value ?

  The SAP error message CN004 ("Enter a numeric value") typically occurs when a user attempts to input a non-numeric value in a field that is expected to contain a numeric value. This can happen in various transactions or screens within SAP, particularly in modules related to finance, controlling, or project management.

  Incorrect Input: The user may have entered letters, special characters, or spaces instead of a number.
  Field Configuration: The field may be configured to accept only numeric values, and any deviation from this will trigger the error.

  Check Input: Ensure that the value you are entering is purely numeric. Remove any letters, special characters, or spaces.

  Review Field Requirements: Check the field's requirements or documentation to understand what type of numeric value is expected (e.g., integer, float).
  Clear and Re-enter: If you suspect that the input might have hidden characters (especially from copy-pasting), try clearing the field and typing the value manually.
