Vendor is not on hold and item is available for usage. Basically, the PO has been modified in which it has already 2 fully invoiced lines and 4 not fully received. User made one change in which he deleted first line as there is mistake in sales tax code and readded the line again. Now, the issue here is we have the confirmation journal for all the 6 lines. But the approval status is still in approved instead of confirmed and the confirm button is grayed out.
