PO/item missing in Report: Purchases->Item->Item purchases[Item details]
After update to 2020.2.23.9038, when run report of Purchases[item details], some POs are missing. the only difference is that these POs are imported from .txt files.
But when add up some other items in the those POs, the items added up appear in the report.
These imported POs are displayed in report of Purchases[item summary] normally.
Sorted out!
The tax code is missing in the txt file been imported. When the code is added to the original file, no such problem.
