Hi. Run test report. Check amount and amount (LCY) to see which is out of balance. Upload a screen shot of the journal so we can check the obvious. Neil
Lines having the same combination of PostingDate+DocNumber must balance, furthermore, you can not them mix - if there are, say, 5 lines sharing the same date+docno they must be entered consecutively.
if auto numbering ford DocNo is used, NAV will even automatically insert the next DocNo for you as soon as previous lines form a balanced document.
