  The SAP error message /SCWM/HUFUNCTIONS088 indicates that a handling unit (HU) already has an identification for a specific type. This typically occurs in the context of handling units in the SAP Extended Warehouse Management (EWM) module, where each handling unit can have various identifiers associated with it, such as serial numbers, batch numbers, or other identification types.
  Cause:
  The error is triggered when you attempt to assign an identification (like a serial number or batch number) to a handling unit that already has that identification type assigned. This can happen in scenarios such as:
  
  Trying to assign a serial number to a handling unit that already has a serial number assigned.
  Attempting to change or update the identification type of a handling unit that is already linked to a different identification.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Identifications:

  Use Correct Identification:
