• What is the cause and solution for SAP error message /SCMB/DM_DLV158 - An ASN with the same delivery date/time exists already ?

  The SAP error message /SCMB/DM_DLV158 indicates that there is an issue with the Advanced Shipping Notification (ASN) process in the Supply Chain Management (SCM) module. Specifically, this error occurs when an ASN with the same delivery date and time already exists in the system. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Duplicate ASN: The primary cause of this error is that an ASN has already been created for the same delivery date and time. This can happen if:
  
  The ASN was mistakenly created multiple times.
  There was a system error or a user error that led to the creation of duplicate entries.
  The same delivery is being processed by different users or systems simultaneously.
  
  
  
  Data Entry Errors: Incorrect data entry or system integration issues may lead to the creation of ASNs with identical timestamps.
  
  
  Solution:
  
  
  Check Existing ASNs: 
  
  Review the existing ASNs in the system for the same delivery date and time. You can do this by using transaction codes like /SCMB/ASN or relevant reports in the SCM module.
  Identify if the ASN is indeed a duplicate or if it is a legitimate entry that needs to be processed.
  
  
  
  Modify ASN: 
  
  If you find that the ASN is a duplicate, you may need to delete or modify the existing ASN to allow for the new ASN to be processed.
  If the ASN needs to be updated, ensure that the delivery date/time is changed to avoid conflicts.
  
  
  
  Error Handling: 
  
  Implement error handling in your processes to prevent duplicate ASNs from being created in the future. This could involve checks in the user interface or backend processes.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to ASN processing for any specific guidelines or updates that may address this issue.
  
  
  
  Contact Support: 
  
  If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They may provide insights based on system logs or specific configurations.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for ASN management, such as /SCMB/ASN, /SCMB/ASN_DISPLAY, and others.
  SAP Notes: Check for any SAP Notes that may address this specific error or provide patches/updates to the SCM module.
  User Training: Ensure that users involved in ASN creation are trained on the correct procedures to minimize the risk of duplicate entries.
  System Integration: If your system integrates with other systems (e.g., EDI), ensure that the integration logic is correctly handling ASN submissions to avoid duplicates.
  
  By following these steps, you should be able to resolve the error and prevent it from occurring in the future.
