Purchase Order Receipt not directed to any Bin "Unable to Check Allocations"

Our team has managed to complete a regular Purchase Order Receipt through the receipt entry screen without directing the part to a specific bin. At the time of the receipt, the part did not have a primary bin in the primary warehouse. The main cause of this was the buyer going into the receipt date fields and backdating the receipt so that they transaction date was correct (delay in entering original receipt from actual arrival date). This screwed up the quantity and the original bin.

  1. I have since tried to move the date back to the original entry date and even dates in the future and in the past but no dice. Clicking save throws an Unable to check Allocation error or a Bin can not be blank error.
  2. I’ve clicked the “To Location” on the line tab and it throws the allocation error
  3. I’ve tried to delete the receipt altogether or just the line and no dice.

Did you ever find an answer to this?
