Thankyou for the prompt reply @Brucanna
I have attached supportive screenshots for your reference.
if you’ve noticed screen 1, I generated a P n L report and the purchase details did not tally with the invoices, so i tried a drill down from the report, and i had to check every invoice manually.
that is when i found out that there were 5 invoices for the month of March was missing.
just to cross check i took a different approach by accessing the purchase invoices through “purchase invoice” section and i performed a search for the particular date, all the exact missing 5 invoices are there,
I hope this helps you rectify the bug.
