  Error Message
  WT738: Net-change flag not set for material &
  
  The ampersand (&) is a placeholder for the material number.
  
  
  Cause
  This error occurs during the warehouse task creation or transfer order processing in SAP Extended Warehouse Management (EWM) or Warehouse Management (WM) when the system tries to process a material for which the net-change flag is not set.
  The net-change flag is a control indicator that tells the system whether changes (like stock movements, posting changes) for a material should be considered for warehouse task creation or transfer order generation.
  If this flag is not set for a material, the system assumes that no net changes have occurred for that material, and therefore, it does not create warehouse tasks or transfer orders for it.
  
  When does this happen?
  
  During stock transfer postings or goods movements involving WM/EWM.
  When the system tries to create warehouse tasks or transfer orders based on stock changes.
  If the net-change indicator is missing or not updated for the material in the warehouse management system.
  
  
  Solution
  
  
  Set the Net-Change Flag for the Material:
  
  The net-change flag is usually set automatically by the system when stock changes occur.
  If it is not set, you may need to manually set or reset it.
  
  
  
  Check and Reset the Net-Change Indicator:
  
  Use transaction LX02 (Display Warehouse Stocks on Hand) or LX03 (Display Storage Bin Stocks) to check stock.
  Use transaction LX04 (Reset Net Change Indicator) to reset the net-change flag for the material in the warehouse.
  Alternatively, in EWM, you may use the relevant monitor or report to reset the net-change flag.
  
  
  
  Reprocess the Warehouse Task Creation:
  
  After resetting the net-change flag, re-run the warehouse task creation or transfer order creation process.
  This should allow the system to recognize the stock changes and create the necessary warehouse tasks.
  
  
  
  Check Customizing and Integration Settings:
  
  Verify that the integration between Inventory Management (IM) and Warehouse Management (WM/EWM) is correctly configured.
  Ensure that the net-change indicator is properly updated during goods movements.
  
  
  
  
  Additional Information
  
  The net-change flag is a key part of the stock synchronization between IM and WM/EWM.
  If this error occurs frequently, it may indicate issues with the update routines or batch jobs responsible for setting/resetting the net-change flags.
  In some cases, custom programs or user exits may interfere with the standard process of setting the net-change flag.
  Always check for any relevant OSS notes or SAP support messages related to this error.
