  Error Message
  WSUBST023: Error while setting/resetting the delivery block for delivery &1
  
  &1 is a placeholder for the delivery document number.
  
  
  Cause
  This error occurs when SAP tries to set or reset a delivery block on a delivery document but fails. The delivery block is a status indicator that prevents further processing of the delivery (e.g., picking, goods issue).
  Common causes include:
  
  Authorization issues: The user or program does not have the required authorization to change the delivery block status.
  Inconsistent delivery status: The delivery document might be in a status that does not allow the block to be set or removed (e.g., already processed or closed).
  Locking conflicts: The delivery document might be locked by another user or process, preventing changes.
  Custom enhancements or user exits: Custom code in user exits or BAdIs that handle delivery block changes might be causing errors.
  Data inconsistencies: The delivery document might have inconsistent or incomplete data preventing the block status change.
  System or database errors: Underlying system issues or database inconsistencies.
  
  
  Solution
  To resolve the error, follow these steps:
  
  
  Check authorizations:
  
  Verify that the user or the background job has the necessary authorizations to change delivery blocks.
  Check authorization objects like V_TVBT_BST or related objects controlling delivery block changes.
  
  
  
  Check delivery status:
  
  Use transaction VL02N or VL03N to display the delivery.
  Verify if the delivery is already processed or closed.
  If the delivery is already goods issued or completed, the block cannot be changed.
  
  
  
  Check for locks:
  
  Use transaction SM12 to check if the delivery document is locked.
  If locked, wait for the lock to be released or coordinate with the user holding the lock.
  
  
  
  Review custom code:
  
  If there are user exits or BAdIs implemented for delivery processing (e.g., USEREXIT_SAVE_DOCUMENT_PREPARE in MV50AFZ1 or BAdI LE_SHP_DELIVERY_PROC), check if they are causing the error.
  Debug the code to identify issues.
  
  
  
  Check system logs:
  
  Use transaction SM21 or ST22 to check for system dumps or errors related to the delivery document.
  
  
  
  Manually reset/set the block:
  
  Try to manually set or reset the delivery block in transaction VL02N.
  If manual change works, the problem might be in the program or interface trying to change the block.
  
  
  
  Database consistency:
  
  Run consistency checks for delivery documents if needed.
  Consult with Basis or SAP support if database inconsistencies are suspected.
