  The SAP error message /ACCGO/MCK_MAINT520 BOM &1 is the active one; deactivation not possible typically occurs when you attempt to deactivate a Bill of Materials (BOM) that is currently active in the system. This can happen in various scenarios, such as when you are trying to make changes to a BOM that is being used in production or is linked to other processes.

  Solution:
  
  Check Usage: Verify if the BOM is being used in any active production orders, sales orders, or other processes. You can do this by checking the relevant transaction codes (e.g., CS03 for displaying BOM).
  Deactivate Dependencies: If the BOM is linked to any active processes, you may need to complete or deactivate those processes before you can deactivate the BOM.
  Change Status: If you need to make changes to the BOM, consider changing its status instead of deactivating it. You can set it to a "not active" status if your business process allows for it.
  Authorization Check: Ensure that you have the necessary authorizations to perform the deactivation. If not, contact your SAP administrator to get the required permissions.
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for managing BOMs to ensure compliance with processes.
