• What is the cause and solution for SAP error message FKKINV155 - Source documents with different currencies in an invoicing unit ?

  The SAP error message FKKINV155 indicates that there are source documents with different currencies in an invoicing unit. This typically occurs in the context of invoicing in the SAP Convergent Invoicing (CI) module, where multiple source documents (like contracts, service orders, etc.) are being processed together, but they have different currencies.
  Cause:
  
  Different Currencies: The primary cause of this error is that the source documents being processed have different currencies. For example, one document might be in USD while another is in EUR.
  Invoicing Unit Configuration: The invoicing unit may not be configured to handle multiple currencies, leading to conflicts when trying to create a single invoice.
  Currency Conversion Issues: If there are issues with currency conversion settings or exchange rates, this can also lead to this error.
  
  Solution:
  
  Check Source Documents: Review the source documents that are being processed together. Ensure that they all have the same currency. If they do not, you may need to separate them into different invoicing units or invoices.
  Adjust Invoicing Unit Settings: If your business process requires handling multiple currencies, check the configuration of the invoicing unit to ensure it can accommodate multiple currencies. This may involve adjusting settings in the SAP system.
  Currency Conversion: If necessary, ensure that the currency conversion settings are correctly configured and that the appropriate exchange rates are available in the system.
  Create Separate Invoices: If the source documents cannot be adjusted to have the same currency, consider creating separate invoices for each currency.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal for detailed documentation on Convergent Invoicing and handling currency issues.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FKKINV (for invoicing) and FKKOP (for processing open items) to troubleshoot and manage invoices.
  User Exits and BAdIs: If your organization has specific requirements, consider using user exits or Business Add-Ins (BAdIs) to customize the invoicing process to handle multiple currencies more effectively.
  Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  By addressing the currency discrepancies and ensuring proper configuration, you should be able to resolve the FKKINV155 error and proceed with invoicing.
