• What is the cause and solution for SAP error message WSTRN018 - Specify either a total quantity or a quantity per site ?

  SAP Error Message:
  
  WSTRN018 - Specify either a total quantity or a quantity per site
  
  Cause:
  This error occurs when you are trying to enter a stock transfer order or a related transaction in SAP, and the system requires you to specify either:
  
  A total quantity for the entire transfer, or  
  A quantity per site (plant/storage location)
  
  However, both fields are either left blank or filled incorrectly, causing the system to be unable to determine the quantity to be transferred.
  In other words, the system expects you to provide either a total quantity for the transfer or detailed quantities per site, but not both or neither.
  
  When does it typically occur?
  
  During creation or processing of stock transport orders (STO) or stock transfer postings.
  When entering delivery quantities in stock transport or intercompany stock transfer scenarios.
  When using transaction codes related to stock transfer like ME21N (Purchase Order for STO), VL10B (Purchase Orders Due for Delivery), or MIGO (Goods Movement).
  
  
  Solution:
  
  Specify either a total quantity in the header or item level quantity field, or  
  Specify quantities per site (plant/storage location) if the transfer involves multiple sites.
  
  Steps to resolve:
  
  
  Check the quantity fields:  
  
  If you want to transfer a total quantity, enter it in the total quantity field and leave the per-site quantity fields blank.  
  If you want to specify quantities per site, enter the quantities in the respective site fields and leave the total quantity field blank.
  
  
  
  Avoid entering both:
  
  Do not enter both total quantity and per-site quantities simultaneously, as this causes ambiguity.
  
  
  Review the transaction screen:
  
  Look for tabs or sections where quantities can be entered per site or as a total and ensure only one method is used.
  
  
  Consult configuration if needed:
  
  If the system behavior is unexpected, check with your SAP MM/SD consultant or configuration team to verify if the system is set up correctly for stock transfers.
