Why is the Document Number Highlighted on the Supplier Payment Inquiry (P042004)?

The system highlights the payment number for one of two reasons:

• The document has generic text associated with it.
  The system highlights only the payment number when generic text exists. Position your cursor next to the payment number and press F14 to view the generic text.
• The payment was issued in an alternate currency. The system highlights both the document type and payment number when the payment is issued in an alternate currency.  An alternate currency is a currency that is neither the foreign nor domestic currency of the voucher. Use Option 1 to view the alternate currency.
