• What is the cause and solution for SAP error message FKKBIX180 - Only lines greater than or equal to 2 are allowed ?

  The SAP error message FKKBIX180 ("Only lines greater than or equal to 2 are allowed") typically occurs in the context of financial transactions, particularly when dealing with document processing in the SAP system. This error indicates that the system expects at least two line items in a document, but only one or none has been provided.
  Cause:
  
  Single Line Item: The most common cause of this error is that the user is trying to post a document (like an invoice or a payment) that contains only one line item. Certain transactions in SAP require at least two line items to ensure proper accounting entries (e.g., a debit and a credit).
  Incorrect Configuration: In some cases, the configuration of the document type or the posting rules may require multiple line items.
  User Error: The user may have inadvertently omitted a line item or not entered the necessary details for a second line.
  
  Solution:
  
  Add a Second Line Item: Review the document you are trying to post and ensure that it contains at least two line items. For example, if you are posting an invoice, you might need to add a corresponding line for the offsetting account (e.g., a revenue account).
  Check Document Type Configuration: If you are consistently encountering this error for a specific document type, check the configuration settings in the SAP system to see if there are any rules that enforce a minimum number of line items.
  Review Posting Logic: Ensure that the logic for posting the document is correct. If you are using a custom program or transaction, verify that it is designed to handle multiple line items appropriately.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the transaction you are working with, as there may be additional requirements or constraints.
  
  Related Information:

  User Training: Ensure that users are trained on the requirements for posting documents in SAP, particularly regarding the need for multiple line items in certain transactions.
