  WS438 - The cash discount base in document currency is &1
  
  Cause:
  This error occurs during the posting of a financial document (usually in Accounts Payable or Accounts Receivable) when the system detects an inconsistency or an unexpected value in the cash discount base amount in the document currency. Specifically, the cash discount base amount calculated or entered is either zero, negative, or does not match the expected value based on the invoice and payment terms.
  Common causes include:
  
  Incorrect or missing cash discount base amount in the document.
  Currency differences or rounding issues causing the cash discount base to be zero or invalid.
  Incorrect configuration of payment terms or cash discount indicators.
  Manual changes or overrides in the document that lead to inconsistent cash discount base values.
  Exchange rate differences affecting the calculation of the cash discount base in document currency.
  
  
  Explanation:
  The cash discount base is the amount on which the cash discount is calculated. It is usually the invoice amount minus any deductions or adjustments. If this base is incorrect, the system cannot correctly calculate the cash discount, leading to this error.
  
  Solution:
  
  
  Check the Document Entries:
  
  Verify the amounts entered in the invoice or payment document.

  Check if the payment terms include valid cash discount percentages and base calculation rules.
  
  
  
  Currency and Exchange Rate:
  
  Verify the currency of the document and the exchange rate used.
  Check for rounding differences that might cause the cash discount base to be zero or invalid.
  If necessary, adjust the exchange rate or rounding settings.
  
  
  
  Recalculate or Adjust the Cash Discount Base:
  
  Use transaction codes like FB02 (Change Document) or FB03 (Display Document) to review and correct the cash discount base.
  If the system allows, manually adjust the cash discount base to a valid amount.
