• What is the cause and solution for SAP error message /SCWM/SERIAL045 - Item &1, HU &2, prod. &3: serial number &4 entered multiple times ?

  The SAP error message /SCWM/SERIAL045 indicates that a serial number has been entered multiple times for a specific handling unit (HU) and product combination. This typically occurs in the context of warehouse management and inventory control within the SAP Extended Warehouse Management (EWM) module.
  Cause:
  The error is triggered when:
  
  A serial number that is supposed to be unique is being assigned to the same handling unit (HU) and product combination more than once.
  There may be a data entry error where the same serial number is mistakenly entered multiple times.
  The system is configured to enforce unique serial number tracking, and the same serial number is being processed in a way that violates this uniqueness.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Serial Number Entries:
  
  Review the entries for the specific handling unit (HU) and product combination to identify where the duplicate serial number has been entered.
  Use transaction codes like /SCWM/PRDI (for product data) or /SCWM/HU (for handling units) to investigate the entries.
  
  
  
  Correct Duplicate Entries:
  
  If you find that the serial number has been entered incorrectly, you will need to correct the data. This may involve deleting the duplicate entry or changing the serial number to a unique one.
  
  
  
  Review Serial Number Management Settings:
  
  Ensure that the settings for serial number management in your SAP EWM configuration are appropriate for your business processes. This includes checking if the system is set to enforce unique serial numbers and if the configuration aligns with your operational needs.
