Smart SAP Assistant

• What is the cause and solution for SAP error message FTR0450 - IDoc no. &1 is not an inbound IDoc; manual linking is not permitted ?

  The SAP error message FTR0450 indicates that the system has encountered an issue with an IDoc (Intermediate Document) that is not recognized as an inbound IDoc. This typically occurs in the context of financial transactions or asset accounting when the system expects an inbound IDoc for processing but finds that the IDoc in question is not suitable for that purpose.
  Cause:
  
  IDoc Direction: The IDoc in question is likely an outbound IDoc rather than an inbound one. Inbound IDocs are those that are received by the system, while outbound IDocs are those that are sent from the system.
  Incorrect Configuration: There may be a configuration issue in the IDoc processing settings, leading to the system misidentifying the IDoc type.
  Manual Linking Attempt: The error may occur if there is an attempt to manually link an IDoc that is not classified as inbound, which is not permitted by the system.
  
  Solution:
  
  Check IDoc Type: Verify the type and direction of the IDoc. You can do this by using transaction WE02 or WE05 to display the IDoc and check its status and type.
  Correct IDoc Processing: Ensure that the IDoc you are trying to process is indeed an inbound IDoc. If it is an outbound IDoc, you will need to find the correct inbound IDoc that corresponds to the transaction you are trying to process.
  Review Configuration: Check the configuration settings for IDoc processing in the relevant modules (e.g., Asset Accounting, Financial Accounting) to ensure that they are set up correctly for inbound processing.
  Reprocess IDoc: If the IDoc is incorrectly classified, you may need to reprocess it or generate the correct inbound IDoc from the source system.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling IDocs in your version of SAP.
  
  Related Information:
  
  IDoc Status Codes: Familiarize yourself with IDoc status codes to understand the processing state of the IDoc.
  Transaction Codes: Use transaction codes like WE02, WE05, and BD87 for monitoring and reprocessing IDocs.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide patches related to IDoc processing.
  Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it.
