• What is the cause and solution for SAP error message GJ955 - Vendor, Customer, and G/L Account Line Items not Allowed at Same Time. ?

  The SAP error message GJ955 ("Vendor, Customer, and G/L Account Line Items not Allowed at Same Time") typically occurs when you are trying to post a transaction that involves multiple types of line items (vendor, customer, and G/L account) in a single document. This is not allowed in SAP because each line item must be clearly defined as either a vendor, customer, or G/L account, and mixing them in one transaction can lead to inconsistencies in accounting.
  Cause:
  
  Mixed Line Items: The primary cause of this error is that the document you are trying to post contains line items that reference different types of accounts (e.g., a vendor account, a customer account, and a G/L account) in the same transaction.
  Transaction Type: Certain transaction types in SAP are designed to handle specific types of accounts. For example, a vendor invoice should only reference vendor accounts and G/L accounts, not customer accounts.
  Configuration Issues: There may be configuration settings in your SAP system that restrict the posting of mixed line items.
  
  Solution:
  
  Review Line Items: Check the line items in your transaction. Ensure that all line items belong to the same category (either all vendor, all customer, or all G/L accounts). You may need to split the transaction into separate postings.
  Separate Transactions: If you need to post transactions involving both vendors and customers, consider creating separate documents for each type of transaction.
  Check Document Type: Ensure that you are using the correct document type for the transaction you are trying to post. For example, if you are posting a vendor invoice, make sure it is set up to only include vendor and G/L accounts.
  Consult Configuration: If you believe the configuration might be causing the issue, consult with your SAP administrator or a functional consultant to review the settings related to account types and document postings.
  
  Related Information:
  
  SAP Documentation: Refer to SAP Help documentation for more details on posting transactions and the rules governing line items.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB60 (Vendor Invoice), FB70 (Customer Invoice), and F-02 (General Ledger Posting) to understand how to properly post transactions.
  Error Logs: Check the error logs for additional details that might help diagnose the issue further.
  User Training: Ensure that users are trained on the proper procedures for posting transactions to avoid this error in the future.
  
  By following these steps, you should be able to resolve the GJ955 error and successfully post your transactions in SAP.
