Day Book Vendor Ledger Entry Report

Any one come across this problem. User posted vendor invoice (euros) then posted the payment under a different rate. Navision worked out the Gain/Loss and posted it. However these transactions are not being picked up by the Day Book report, even with the VLE & G/L Entry options ticked on the request form. The DataItemLink between the VLE & GLE is the “Transaction No.” field, the number on the Payment entry is different to that on the gain/loss postings. The Document No. is the same for all entries so Navigate works ok. Navision version is 3.7A.
