• What is the cause and solution for SAP error message ME418 - Aggregated records inserted into original table ?

  The SAP error message ME418, which states "Aggregated records inserted into original table," typically occurs in the context of purchasing documents, particularly when dealing with purchase orders or purchase requisitions. This error indicates that the system has detected that aggregated records (i.e., multiple line items that have been combined) are being inserted into the original table, which is not allowed in certain scenarios.
  Cause:
  
  
  Data Aggregation: The error often arises when there is an attempt to aggregate multiple line items into a single entry in a table that expects individual records. This can happen during the processing of purchase orders or requisitions where the system expects each line item to be distinct.
  
  
  Custom Code or Enhancements: If there are custom developments or enhancements in the system that manipulate the data before it is saved, they may inadvertently cause this error by trying to aggregate records incorrectly.
  
  
  Configuration Issues: Incorrect configuration in the purchasing module or related settings can lead to this error, especially if the system is not set up to handle certain types of data aggregation.
  
  
  Solution:
  
  
  Review Data Input: Check the data being input into the system. Ensure that the records being processed are not being aggregated incorrectly. Each line item should be distinct and should not be combined unless explicitly allowed.
  
  
  Check Custom Code: If there are any custom programs, user exits, or enhancements that manipulate purchase order data, review them to ensure they are not causing the aggregation of records. Debugging the code may help identify the issue.
  
  
  Configuration Review: Review the configuration settings in the purchasing module. Ensure that the settings related to document types, item categories, and other relevant configurations are correctly set up to allow for the expected behavior.
  
  
  SAP Notes and Support: Check for any relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide fixes or workarounds for known issues. If necessary, contact SAP support for assistance.
  
  
  Testing: After making any changes, conduct thorough testing to ensure that the issue is resolved and that no new issues have been introduced.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ME21N (Create Purchase Order), ME22N (Change Purchase Order), and ME23N (Display Purchase Order) to understand where the error may be occurring.
  Debugging: Use the debugging tools in SAP to trace the execution of the program when the error occurs. This can provide insights into where the aggregation is happening.
  Documentation: Review SAP documentation related to purchasing processes and error handling to gain a better understanding of how to manage and troubleshoot such issues.
