  SAP Error Message:
  
  VO018 - Place the cursor on the wave to which you want to reassign
  
  Cause:
  This error occurs in the SAP Extended Warehouse Management (EWM) or Warehouse Management (WM) module during wave management or warehouse order processing. It typically appears when you try to reassign warehouse orders or tasks to a wave, but the system cannot determine the target wave because the cursor (selection) is not placed on any wave in the wave list or wave overview screen.
  In other words, the system expects you to select (place the cursor on) a specific wave before performing the reassignment, but no wave is selected.
  
  When does it occur?
  
  When you attempt to reassign warehouse orders or warehouse tasks to a wave without selecting a wave.
  During wave processing or wave management transactions (e.g., /SCWM/WAVE, /SCWM/WO, or related screens).
  When using functions like "Reassign to Wave" or similar actions in the wave management UI.
  
  
  Solution:
  
  
  Select the Wave Properly:
  
  Before performing the reassignment, make sure you have placed the cursor (highlighted the row) on the wave to which you want to assign the warehouse order or task.
  In the wave overview screen, click on the wave line to select it. The system requires this selection to identify the target wave.
  
  
  
  Check User Interface:
  
  Ensure you are in the correct screen and that the wave list is visible.
  Sometimes, the UI might not refresh properly; try refreshing the screen or re-entering the transaction.
  
  
  
  Use Correct Transaction / Screen:
  
  Use the standard SAP EWM wave management transactions or apps.
  Follow the standard procedure for wave reassignment.
  
  
  
  Authorization Check:
  
  Verify that you have the necessary authorizations to perform wave reassignment.
  
  
  
  Technical Check (if issue persists):
  
  If the error persists despite selecting a wave, check for any custom enhancements or user exits that might interfere with the standard behavior.
  Check for OSS notes related to wave management and error VO018.
