• What is the cause and solution for SAP error message FQ644 - Request may only contain a single FI document ?

  The SAP error message FQ644 ("Request may only contain a single FI document") typically occurs in the context of financial document processing, particularly when dealing with the integration of financial accounting (FI) documents in SAP. This error indicates that the system is expecting only one financial document in the request, but it has detected multiple documents instead.
  Cause:
  
  Multiple Documents in a Single Request: The primary cause of this error is that the request being processed contains more than one financial document. This can happen if a batch job or a manual entry inadvertently includes multiple documents in a single transaction.
  Incorrect Configuration: Sometimes, the configuration settings in the system may allow for multiple documents to be processed together, which can lead to this error if the system is not set up to handle it.
  Data Entry Errors: Users may accidentally select multiple documents when trying to process a single document.
  
  Solution:
  
  Check the Request: Review the request that triggered the error. Ensure that it contains only one financial document. If multiple documents are included, separate them into individual requests.
  Adjust Batch Jobs: If this error occurs during batch processing, check the batch job configuration to ensure that it is set up to handle only one FI document at a time.
  User Training: Provide training to users on how to correctly enter and process financial documents to avoid selecting multiple documents inadvertently.
  System Configuration: If necessary, consult with your SAP Basis or configuration team to review the settings related to financial document processing to ensure they align with your business requirements.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB01 (Post Document), FB50 (G/L Account Document), and FBL1N (Vendor Line Item Display) to understand where the error might be occurring.
