13 years later and this issue arises for us. I too would like to know the resolve of this.
UPDATE: After filing a ticket with Infor the resolve is that Infor stated to us they can't recreate the error and they don't know where it stems from. They offered a patch they stated works for 'some' clients. But we're not patching just to be patching. The anomoly has corrected itself because PO20 is running fine the next day for all our facilities.
