• What is the cause and solution for SAP error message /SCWM/WAVE181 - Wave Update failed - Cancel Picking is possible for &1 &2 only ?

  The SAP error message /SCWM/WAVE181 Wave Update failed - Cancel Picking is possible for &1 &2 only typically occurs in the context of the SAP Extended Warehouse Management (EWM) module when there is an attempt to update a wave that is currently in a state that does not allow for the cancellation of picking activities. 
  Cause:
  This error message indicates that the wave you are trying to update has picking activities that cannot be canceled. The placeholders &1 and &2 in the error message usually represent specific identifiers related to the wave or the picking activities. The reasons for this error can include:
  
  Picking Status: The picking process for the items in the wave may have already progressed to a stage where cancellation is not allowed (e.g., items have been confirmed as picked).
  Wave Status: The wave itself may be in a status that does not permit changes or cancellations.
  System Configuration: There may be specific configurations or settings in the system that restrict the cancellation of picking for certain types of waves or items.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Wave Status: Review the status of the wave in question. If the wave is already completed or in a status that does not allow for changes, you may need to create a new wave or adjust the existing one accordingly.
  
  
  Review Picking Status: Check the picking status of the items involved. If the items have already been confirmed as picked, you may need to follow the appropriate process for handling confirmed picks rather than attempting to cancel them.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines regarding wave management and picking processes to understand the specific conditions under which cancellations are allowed.
  
  
  System Configuration: If you suspect that the issue may be related to system configuration, consult with your SAP EWM administrator or technical team to review the settings related to wave processing and picking.
  
  
  Error Logs: Check the system logs for any additional error messages or warnings that may provide more context about the failure.
  
  
  Testing: If possible, test the wave update process in a development or test environment to replicate the issue and identify the exact cause.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error message or provide guidance on wave management in EWM.
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM, such as /SCWM/WAVE for wave management and /SCWM/PR for picking requests.
  User Roles: Ensure that the user attempting to perform the wave update has the necessary authorizations to make changes to waves and picking activities.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it. If the issue persists, consider reaching out to SAP support for further assistance.
