To display the narrative on reports and layouts, e.g. Purchase Remittance, requires the inclusion of the NLPostedNominalTran/NLDeferred NominalTran/NLPendNominalTran table(s) (depending on system configuration) by joining on the UniqueReferenceNumber. It would be be more efficient if the Narrative field was in the PLPostedSupplierTran, SLPostedCustomerTran and CBPostedAccountTran, depending on the source of the posting.
