• What is the cause and solution for SAP error message NAA155 - Supplier bill doc. &1 is a pro forma doc.(no provision for accr. income) ?

  The SAP error message NAA155 indicates that the system has identified a supplier bill document as a pro forma document. Pro forma invoices are typically used for informational purposes and do not have the same accounting implications as standard invoices. This means that the system does not allow for the accrual of income against this type of document.
  Cause:
  The error occurs because:
  
  The document in question is classified as a pro forma invoice, which is not intended for actual accounting entries.
  The system is trying to process this document in a way that requires it to be treated as a standard invoice, which is not permissible for pro forma documents.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Verify Document Type: Check if the document is indeed a pro forma invoice. If it should not be, you may need to change the document type or create a new standard invoice.
  
  
  Correct Document Entry: If the document is correctly classified as a pro forma invoice, ensure that you are not trying to perform actions that are only valid for standard invoices, such as posting accruals.
  
  
  Review Configuration: If pro forma invoices are being used incorrectly in your process, review the configuration settings in SAP to ensure that the document types are set up correctly and that users are aware of the limitations of pro forma invoices.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines regarding the handling of pro forma invoices to ensure compliance with accounting practices.
  
  
  User Training: If users are frequently encountering this error, consider providing training on the differences between pro forma and standard invoices, and the appropriate scenarios for each.
  
  
  Related Information:
  
  Pro Forma Invoices: These are often used in international trade and for preliminary billing. They do not represent a true financial transaction until a standard invoice is issued.
  Accrual Accounting: Understand the principles of accrual accounting, which require that income and expenses be recorded when they are earned or incurred, not necessarily when cash is exchanged.
  SAP Documentation: Check SAP Help Portal or your organization's SAP support resources for more detailed information on handling invoices and error messages.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a financial consultant familiar with your specific SAP configuration.
