  The SAP error message IDGT_LC171, which states "Cannot combine documents of different exchange rate or foreign currency," typically occurs in scenarios where you are trying to process or combine financial documents (such as invoices, payments, or journal entries) that involve different currencies or exchange rates. This can happen in various SAP modules, particularly in Financial Accounting (FI) or Controlling (CO).
  Cause:

  Use Currency Conversion: If applicable, use SAP's currency conversion functionality to convert the amounts to a common currency before attempting to combine the documents.
  Review Document Types: Check if the document types you are working with have any specific restrictions regarding currency and exchange rates. You may need to use a different document type that allows for the combination.
