• What is the cause and solution for SAP error message MM_PUR_PO_EXT_MSG000 - Delta Import cannot be done before Full Import. ?

  The SAP error message MM_PUR_PO_EXT_MSG000 indicates that a delta import cannot be performed before a full import has been completed. This error typically arises in the context of SAP's data transfer processes, particularly when dealing with the integration of purchase order data.
  Cause:
  
  Data Transfer Process: In SAP, data is often transferred in two stages: a full import and delta imports. A full import is necessary to establish a baseline of data, while delta imports are used to update that data incrementally.
  Missing Full Import: The error suggests that the system is attempting to perform a delta import without having first completed a full import. This is a prerequisite for delta imports to ensure that the system has a complete and accurate dataset to work from.
  
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Perform a Full Import:
  
  Ensure that a full import of the relevant data has been executed successfully. This may involve running a specific transaction or program in SAP that handles the full import of purchase order data.
  Check the logs or status of the full import to confirm that it completed without errors.
  
  
  
  Check Data Transfer Settings:
  
  Review the configuration settings for the data transfer process to ensure that the sequence of operations is correctly set up. This includes verifying that the full import is scheduled or triggered before any delta imports.
  
  
  
  Monitor Data Load Processes:
  
  Use transaction codes like SM37 (Job Monitoring) to check for any background jobs related to the data import process. Ensure that the jobs are running in the correct order.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific module you are working with (e.g., MM - Materials Management) for any additional guidance or troubleshooting steps.
  
  
  
  Contact SAP Support:
  
  If the issue persists after performing a full import and checking the settings, consider reaching out to SAP support for further assistance. They may provide insights specific to your system configuration or version.
  
  
  
  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) for managing purchase orders.
  Data Transfer Methods: Understand the different methods of data transfer in SAP, including IDocs, BAPIs, and direct table updates, as these can affect how data is imported and managed.
  SAP Notes: Search for SAP Notes related to the error message or the specific module you are working with, as they may contain patches or updates that address known issues.
  
  By following these steps, you should be able to resolve the MM_PUR_PO_EXT_MSG000 error and successfully perform the necessary data imports in your SAP system.
