• What is the cause and solution for SAP error message WS597 - Points without a unit are not allowed. Check input data ?

  SAP Error Message:
  
  WS597 - Points without a unit are not allowed. Check input data
  
  Cause:
  This error occurs when a quantity or a measurement point is entered in a transaction or master data without specifying the corresponding unit of measure. In SAP, whenever you enter a quantity or a measurement value (e.g., in production orders, inspection lots, or quality notifications), the system requires a unit of measure to interpret the value correctly. If the unit is missing or not maintained, the system throws this error.
  Common scenarios where this error appears:  
  
  Entering inspection results or quality data points without specifying the unit.  
  Creating or changing production orders or process orders where quantities are entered without units.  
  Data entry in Quality Management (QM) where measurement points require units.  
  Master data maintenance where units are mandatory but missing.
  
  
  Solution:
  
  
  Check the Input Data:
  
  Review the data entry screen where the error occurs and ensure that every quantity or measurement point has an associated unit of measure.
  
  
  Maintain Units of Measure:  
  
  If the unit field is empty, enter the correct unit (e.g., KG, M, L, PCS).  
  If the unit is not available in the dropdown or selection list, you may need to create or extend the unit of measure in the system.
  
  
  
  Verify Master Data:  
  
  Check the material master (MM03) for the base unit of measure and other relevant units.  
  Check the inspection characteristic or measurement point master data in QM to ensure units are assigned.
  
  
  
  Check Configuration:  
  
  In Quality Management, verify that the inspection characteristics have units assigned in transaction QS21 (Change Inspection Characteristic).  
  Ensure that the unit of measure is consistent across related master data and transactional data.
  
  
  
  Data Uploads or Interfaces:  
  
  If data is being uploaded via LSMW, BAPI, or interfaces, ensure that the unit of measure field is correctly populated in the source data.

  Summary:
  Error WS597 is triggered when a quantity or measurement point is entered without a unit of measure. To resolve it, always ensure that units are specified and maintained in both master data and transactional data. Check the relevant master data, input screens, and configuration to maintain consistency and completeness of units of measure.
