• What is the cause and solution for SAP error message FQ790 - Coding block not possible: Several G/L account lines exist ?

  The SAP error message FQ790, which states "Coding block not possible: Several G/L account lines exist," typically occurs during the processing of financial documents, such as invoices or payments, when there are multiple General Ledger (G/L) account lines involved in a transaction. This error indicates that the system cannot process the transaction because it requires a single G/L account line for coding.
  Causes:
  
  Multiple G/L Accounts: The transaction involves multiple G/L account lines, which is not allowed in certain contexts (e.g., when trying to post a document that requires a single G/L account).
  Document Type Restrictions: The document type being used may have restrictions that prevent multiple G/L accounts from being processed together.
  Configuration Issues: There may be configuration settings in the SAP system that restrict the posting of transactions with multiple G/L accounts.
  Incomplete Data: The transaction may be missing required information or may have been incorrectly set up, leading to multiple G/L accounts being referenced.
  
  Solutions:
  
  Review the Document: Check the document you are trying to post. Ensure that it only references a single G/L account line. If there are multiple lines, consider splitting the transaction into separate postings.
  Change Document Type: If applicable, consider using a different document type that allows for multiple G/L accounts, if your business process allows for it.
  Configuration Check: Consult with your SAP administrator or functional consultant to review the configuration settings related to the document type and G/L account postings. Adjustments may be needed to allow for multiple G/L accounts if that is appropriate for your business process.
  Error Analysis: Use transaction codes like FB03 (Display Document) to analyze the document and see the details of the G/L account lines involved. This can help identify why multiple lines are being created.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the error message and related configurations.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB01 (Post Document), FB03 (Display Document), and FBL1N (Vendor Line Item Display) to analyze and manage financial postings.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP Notes can provide additional context or solutions for specific scenarios.
  User Roles and Permissions: Ensure that the user has the appropriate roles and permissions to perform the transaction, as restrictions may also lead to errors.
  
  If the issue persists after trying the above solutions, it may be beneficial to engage with your SAP support team or a consultant for further assistance.
