Mtl Seq line closed before it's time

"I have a material seq line in a job that was marked issue complete by a
receiver. This receiver has been invoiced so I can not delete and re-enter.
I still need to receive to the material seq line. Is there a way to re-open
this line"

Even if the Receiver has been invoiced, you can still 'Update' the line
item, and uncheck the Received Complete check box. This will reopen the po
line item for you and allow you to make additional receipts against the line
