"DIRECT DEBIT PAYMENT" expense transactions coming from Corporate Card Integration files
I noticed that while working in Oracle Fusion Corporate card Integration with a bank that there are some MasterCard transactions that come in the bank XML File having value like "C" for attribute "CurrencySign" under XML tag <TotalTaxAmount>. That cause transaction to be imported to the application with negative values for the corporate card transactions and AP invoices as well.
Moreover, all these transactions have <AdjustmentDescription> tag value as "DIRECT DEBIT PAYMENT". I tried to search on Oracle Support and Customer Connect for anything explaining this kind of transactions, but I didn't find anything.
Could you help me please to know more and understand that kind of transaction and the justification behind making it? (is it Refunds or related to something else).
