• What is the cause and solution for SAP error message WS592 - Weights without units are not allowed. Check input data ?

  SAP Error Message:
  
  WS592 - Weights without units are not allowed. Check input data
  
  Cause:
  This error occurs when a weight value is entered or processed in SAP without an associated unit of measure (UoM). In SAP logistics and materials management, every weight must have a corresponding unit (e.g., KG, LB). If the system encounters a weight value but the unit field is empty or missing, it triggers this error to prevent inconsistent or incomplete data entry.
  Common scenarios causing this error include:
  
  Missing weight unit in material master data.
  Weight unit not maintained in the transaction (e.g., delivery, goods movement).
  Incorrect or incomplete data upload via interfaces or batch input.
  Custom programs or user exits passing weight values without units.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Check the Basic Data or Additional Data views for the weight and weight unit fields.
  Ensure that the weight unit (e.g., KG) is maintained correctly.
  
  
  
  Verify Transaction Data:
  
  In the transaction where the error occurs (e.g., VL01N for delivery creation), verify that the weight unit is entered along with the weight.
  If entering data manually, ensure the weight unit field is not left blank.
  
  
  
  Data Upload / Interface Checks:
  
  If data is uploaded via IDocs, BAPIs, or batch input, verify that the weight unit field is populated.
  Check mapping and conversion routines to ensure weight units are correctly passed.
  
  
  
  Custom Code / User Exits:
  
  Review any custom enhancements or user exits that manipulate weight data.
  Ensure that weight units are always assigned when weights are set.
  
  
  
  Configuration:
  
  Check the unit of measure settings in SPRO under Logistics ? General ? Units of Measure.
  Confirm that the relevant weight units are defined and active.
  
  
  
  
  Related Information:
  
  Transaction Codes: MM03, VL01N, VL02N, VL10B, LT01, etc.
  Tables: MARA (Material Master), MARM (Units of Measure for Material), LIPS (Delivery: Item data)
  Notes: SAP OSS Notes related to WS592 may provide specific fixes or patches if the error is due to a system bug.
  Weight Unit Field: Usually the field GEWEI in material master or delivery item.
  Best Practice: Always maintain consistent units of measure for weights in master data and transactional data to avoid such errors.
  
  
  Summary:
  Error WS592 is triggered because SAP requires every weight value to have an associated unit of measure. To resolve it, ensure that the weight unit is properly maintained in the material master and entered in all relevant transactions or data uploads. Check custom code and configuration if the problem persists.
