• What is the cause and solution for SAP error message SE310 - Combination of bidder's line and supplementary line not allowed ?

  The SAP error message SE310, which states "Combination of bidder's line and supplementary line not allowed," typically occurs in the context of procurement processes, particularly when dealing with bids or quotations in the SAP system. This error indicates that there is an issue with how the bid lines are structured or combined in the system.
  Cause:
  
  
  Bidder's Line vs. Supplementary Line: The error arises when there is an attempt to combine a bidder's line (which represents the main offer from a supplier) with a supplementary line (which may represent additional information or conditions related to the bid). SAP does not allow these two types of lines to be mixed in a single transaction or document.
  
  
  Configuration Issues: There may be configuration settings in the SAP system that dictate how bids and supplementary lines should be handled. If these settings are not aligned with the business process, it can lead to this error.
  
  
  Data Entry Errors: Incorrect data entry or selection of lines in the bidding process can also trigger this error. For example, if a user inadvertently tries to add a supplementary line to a bidder's line.
  
  
  Solution:
  
  
  Review Bid Structure: Ensure that the bid or quotation is structured correctly. Separate bidder lines from supplementary lines. If you need to add supplementary information, do so in a manner that does not combine them with the main bidder's line.
  
  
  Check Configuration: Consult with your SAP configuration team to review the settings related to bidding and quotations. Ensure that the system is configured to handle the types of lines you are trying to use appropriately.
  
  
  Data Entry Validation: Implement validation checks during data entry to prevent users from inadvertently mixing bidder lines with supplementary lines. This can include training for users on how to properly enter bids and quotations.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling bids and supplementary lines. This can provide insights into best practices and system limitations.
  
  
  Error Logs: Check the error logs for more detailed information about the error. This can help identify the specific conditions under which the error occurs.
  
  
  Related Information:
  
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide patches or updates that could resolve the issue.
  User Forums: Engage with SAP user communities or forums where similar issues may have been discussed. Other users may have encountered the same error and can provide insights or solutions.
  Training: Consider providing additional training for users involved in the procurement process to ensure they understand how to properly enter and manage bids and supplementary lines.
